2B E-Stim Control Unit Review from E-Stim Systems

A Review Three Months & Countless Orgasms In The Making

I have been enjoying e-stim for about two years now and I really enjoy passing on my thoughts and views in my reviews of the e-stim products that I have enjoyed. I tend to only review quality items and shy away from the cheap and dangerous items you find on e-bay and amazon. So far I have only reviewed products for two UK based companies and this control unit comes from one of them, E-Stim Systems. I own three other control units from these guys and they are all amazing and ever since I started my journey of discovery into the kinky world of electrosex I have set my sights on reviewing the 2B as I had heard so many great things about it.

I have finally managed to get one in to review and it's taken me three months to get into the position where I could publish this review. That's because every time I sit down to write this review I decide to give it one more try - just for research purposes. That's my excuse and I am sticking to it. There is just so much to talk about with this incredible electrosex control unit and I will attempt to lay out my thoughts on it in a logical manner in this review.

I enjoy using an insertable bipolar electrode either vaginally or anally together with adhesive pads on either side of my vulva about inline with my clitoris (I am sure you can form a picture in your head without me needing to draw one). This combination of internal and external stimulation feels incredible for me and being able to set different output settings for each channel is fantastic. I have lost count of the number of hours that have flown by whilst I have been masturbating, I mean doing my research for this review.

Please bear with me though as this review might get a bit long and also techy in places but I don't apologise for that at all. If you're thinking about spending some serious money on a new control box you need to know the ins and outs of your potential new purchase before parting with your hard earned cash. So with the benefit of countless orgasms at the hands of this incredible control unit lets get on with my review of the 2B E-Stim Control Box.

As this is such a long review I thought that I should make some quick links just in case anyone wants to jump to a particular section without having to read it in full. I do recommend that you read the whole review though so that you get a balanced view of the 2B control box and of the Bonus Pack:

Delivery

The 2B comes in a very handy storage boxIt might not be of much interest to some readers but for others it will be a huge concern which is why I am going to mention it here. When you buy anything from E-Stim Systems your purchase always arrives quickly and within very discreet packaging. I have had numerous deliveries from them now and they have never let me down. So if you are concerned about discretion with your delivery then you needn't worry it will be fine.

As well as being discreet the packaging also does a good job of protecting your purchase and I have never received anything that was damaged on route, which is amazing as I sometime think that my local post office has an internal rugby league thing going on judging by the condition of the packaging on some toys I have received to review.

I do like the storage box that the 2B control box comes in, all of the kit is stored inside and the outer advertising can be removed to just leave the black box with E-Stim Sytems in yellow emblazoned on it. Mine is one of the old style boxes, the new ones are much more stylish but they serve the same purpose.

The 2B in all of its glory is quite a smalle unit

What Is The 2B?

The control box is the heart of an e-stim systemIn a nutshell the 2B is an e-stim control box and the control box or unit is the core of any electrosex activity, it provides a safe current to the electrodes that you are using to allow you to experience pleasure or pain and everything between the two. If you are new to the world of E-Stim then check out this article - Beginners Guide To E-Stim From a Female Prospective for a quick introduction to the activity. The 2B is CE approved and safe to use, E-stim Systems have put a lot of thought into the safety aspects of electroplay.

The 2B has a lifetime guaranteeThe 2B has dual isolated channels (so you can connect two different electrodes and operate them independently) and it features 17 operating modes with 2 audio modes. It also includes a built in microphone. The front face has a backlit two line display, three knobs and a tactile button and it is powered by either a 9v PP3 battery or by mains using the included universal adaptor. It has a BiPhasic AC output and through the Digital Link System you can control it through a PC or Mac or even over the internet. There are two output sockets on the right hand side of the unit and these outputs have corresponding LED lights next to them to indicate current flow. It has a socket for a power cable next to the on/off switch which is located on the lower edge of the unit.

E-Stim Systems also offer a lifetime guarantee on the 2B and also free shipping within the UK and Europe which is great news.

Package Contents

The 2B Power Box is available for purchase on its own as just a control unit for just £299 which is great if you already have a lot of e-stim equipment and you want to upgrade just your control box. I opted for the 2B Bonus Pack at £378 as this comes with extra leads for my existing electrodes and also the Digital Link System - more on that later in the review. I opted for this kit as I wanted to review all of the capabilities of the 2B.

The 2B bonus pack is full of excellent goodiesThe 2B Bonus Pack comes with:

  • 1 x 2B Control Box
  • 4 x Self Adhesive Electrode Pads
  • 2 x 3.5mm to 2mm output cables
  • 2 x 3.5mm to 4mm output cables
  • 1 x 3.5mm Stereo input cable
  • 1 x USB Digital Link Interface
  • 1 x 4GB USB Stick
  • 1 x PP3 Battery
  • 1 x Audio CD
  • 1 x Carry Case
  • 1 x Mains power supply
  • User guide

Performance & Use

Well to start with I will just state for the record that the 2B blew me away in terms of both its functionality and its features. In use though you really get to appreciate the range of sensations that it can deliver from gentle tickling sensations to full on cramps and pain. It is highly controllable and the controls are very easy to use and understand. You switch it on after either inserting a PP3 9V battery (included) or connecting it to the included mains adaptor. The blue display then lights up and the unit goes through a short self test phase where it tells you which firmware update it is running (mine was initially on version 2.104). If you do use the mains adaptor you can expect an increase in the output power of about 30% and obviously you then won't have to worry about the battery running flat during a long play session.

The 2B is mains or battery operatedI like using a battery though as it means one less cable to get caught up in as lets face it there are enough cables already when you are using both channels and maybe the audio input. The only gripe I have about the 2B is the rattly battery in its compartment. I know it's a small picky thing and I'm very tempted to cut up a small piece of foam and stick in my battery compartment to keep the blinking thing quiet. I guess it's one thing that you have to expect with a battery that you can change yourself instead of having an internal fixed rechargeable battery. I like having the ability to change batteries though instead of having to wait to recharge internal batteries so it's something that whilst being just a small niggle for me I am more than happy to put up with.

The 2B features a two line display that is easy to readIt has two operating power levels which is great for both beginners and power queens. It's very simple to switch from one to the other through the settings menu. During use you will see a letter 'L' or 'H' in the center of the display to let you know which operating power-band it is currently set to 'Low' or 'High'. This setting is remembered between uses even after removing the battery so once you find which one works best for you then you don't have to worry about constantly having to set it up again each time you use the 2B. As an e-stim wuss I found the lower power level perfectly fine for my tastes but I have played with the high levels usually in a BDSM scene for some truly demonic sessions.

The 2B has two outputs and one inputIn use you can quickly move from program to program efficiently through the intuitive menu and you soon get a hang of using just the three knobs and the tactile button. Having two outputs gives great flexibility for using multiple electrodes or you can even hook up two people at the same time if that's your thing. I enjoy using an insertable bipolar electrode either vaginally or anally together with adhesive pads on either side of my vulva about inline with my clitoris (I am sure you can form a picture in your head without me needing to show you a picture). This combination of internal and external stimulation feels incredible to me and being able to set different output settings for each channel is fantastic as I can fine tune each set of electrodes. I have lost count of the number of hours that have flown by whilst I have been masturbating, I mean doing my research for this review.

Now to give you an example of how easy the 2B is to operate, I had it hooked up and I had been using it on and off for about two weeks experiencing some incredible orgasms before I even opened the instructions (yes I know - naughty Joanne, very bad reviewer Joanne). What I am trying to say is that it's so easy to use that it's only when you want to explore the true power and flexibility of the 2B and you want to experiment with the Digital Link System that you even need the instructions. Anyone can basically get it working straight out of the box and for something as technically advanced as the 2B that's testimony to how much effort has gone into the simple but extremely effective user interface and menu. That said though when you do open the manual up and start reading it you'll find it well written and easy to understand and it covers all areas of the 2B's operation and functionality.

The sensations generated by this control box can be much more intense than those generated by my ElectroPebble or ElextroHelix. The way that you can easily adjust the output and ramp it up by percentage of total output is great and it makes it very easy to find the exact setting that tips you over the edge into a true hands free orgasm.

The 2B has an easy to understand interfaceWith seventeen set programmes to enjoy and use you will never get bored. My personal favourites are 'Waterfall' and 'Squeeze', these two for me at least are best served with a large bipolar electrode enjoyed vaginally and it feels amazing. There is so much power in the 2B I can only use mine on the lower setting upto around 70% depending on the electrode that I'm using and its position. The high setting must be a real dream for all the electro-queens out there or for use on errant submissives. I can see the 2B taking pride of place in any Dominatrix's dungeon as a means of tormenting their subs before delivering hands free orgasms to those that deserve that special treat. Add some restraints to your e-stim play and you can really spice things up a lot.

The 2B has an internal microphone and also the ability for you to attach it to any music player by a standard 3.5mm socket and it will translate your music and songs into extremely enjoyable pulsed output, this is very effective indeed. The machine also comes with a CD full of specially designed audio tracks that maximise this function of the 2B and this was a real eye opener for me in that it outperformed my expectations so make sure that you give this feature a try. You can tweak the sensitivity and output through the settings menu to tailor the audio to your requirements and it's a lot of fun. Having the internal microphone means that it can be used to punish a submissive for example if he or she simply makes a noise so it can be used with music or for some serious BDSM fun and games.

Top Tip: In audio mode you can have a lot of fun with an insertable Bi-polar electrode and a crop or paddle with the 2B delivering pulses in time with the blows on your submissive's behind, even their squeals of delight or groans of despair will illicit a shock.

I like the way that the housing for the 2B is an off the shelf box that has been expertly machined in house to contain the 2B rather than a bespoke design, this keeps costs down for the customer and also means that E-Stim Systems have complete control over the manufacturing process at their manufacturing facility in Watford. Whilst the 2B does have a hefty price tag when you mentally break it down in terms of what it takes to hand make something like this you will see that it is actually very good value for money as it has exceptional features and continues to be developed.

The 2B is one hell of a good e-stim control box

Digital Link Interface

I love the branded usb thumbdriveThe Digital Link Interface is a USB driver that allows you to connect your 2B control box to your PC or Mac using a USB cable. Whilst that might not sound all that exciting at first when you realise that it then allows you to do lots of clever things like install the latest firmware yourself without having to return your 2B to E-Stim Systems as well as allowing control of your 2B through your computer using the Commander software or even controlling it from afar over the internet.

The commander software and bootloader all come on a very smart little branded USB that I love. It contains all of the files and instructions for adding the commander software and drivers so that your set-up should be flawless. You can always fall back on the excellent customer support from E-Stim Systems (which is excellent) if you do have an issue getting it working at your end.

I decided to upgrade my 2B to the latest firmwareThe instructions for installing the driver for the Digital Link Cable were easy to follow and on my Windows PC it was pretty much plug and play with Windows automatically installing the drivers that I needed.

Just the ability to update the firmware (or internal operating system) of the unit means that you can easily keep your machine in tune with new developments of its features and capabilities to address any problems or improvements that E-Stim Systems make to the 2B and I put that feature to the test as well.

As I stated at the start of this review my 2B was Version 2.104 and so I decided to download the latest firmware version from E-Stim Systems and I tested just how easy it is to update your control box. Once I had downloaded the new Firmware I installed the Uplink 2.1 software which is included on theThe uplink 2.1 software made it easy to update my 2B USB memory stick and it's also available on the manufacturers website. I followed the included instructions and connected my 2B before telling the Uplink to update my control box. Six minutes later I was given a success message and my 2B Control Box is now running the latest firmware Version 2.105, it was simplicity itself and this demonstrates a key feature of the 2B, its upgradeability.

Now just a final comment on the versatility of the 2B, the manufacturers website has an excellent forum for exchanging ideas and advice on all things e-stim and there are several software developers actively working on ways to increased the functionality of the 2B and all of this is free to check out and enjoy. Visit the E-Stim Forum.

Commander Software

The Commander software is very easy to useThe Commander software is very easy to install and use, it is also extremely easy to understand and it is this software that really allows you to do some amazing things with your 2B. Apart from being able to control your 2B from the Commanders graphical user interface which is easier to use than the built in menu system on the 2B you can use this software to either control another 2B remotely or you can allow someone to control your 2B remotely which is a very interesting concept for lets say online Dominatrix's or anyone in a long distance relationship (LDR).

Once installed I just connect my 2B to the Digital Link Cable and then switch it on before opening up the Commander software to play. It connects straight away and I like the way that all of the most frequently needed controls are all on the same page and it's very easy to switch programs and power levels. The Commander can be set as either a Master or Slave if you are doing a remote session and that is basically telling it which Comander program is the one connected to the 2B and which one acts as the controller.

It is the Commander software and its ability to allow remote control that really adds a new dimension to the 2B, it means that if you are in a LDR or provide webcam services for instance you can use the 2B with it being controlled by someone from anywhere in the world as long as they have an internet connection. As it is a peer to peer setup when using the 2B your data and usage is never seen by the manufacturers and this is worth noting in this era of data mining and data analysis. Your details are secure and your data is never shared with a third party, this is a principle that some big manufacturers have paid lip-service to and the public and financial backlash have been huge for them. E-Stim Systems have been very ethical in their approach to this concern and they are to be commended for that.

Third Party Apps and Files

There is a thriving community of developers for the 2B and most developers post updates on the E-Stim Systems main forum so keep checking the forum if you own one. Here is one of the best resources for files and build projects and it is well worth checking out. Check out Nigels E-Stim Page.

I wouldn't recommend this control box to anyone who:

  • Cannot justify the price.

Final Thoughts

This review has been a real voyage of discover for me, I have learnt that not all control boxes are created as equals. The 2B is the prestige control box that I imagined it would be, its extensive functions and features still blow me away and even after three months of using it I am still finding new ways to enjoy it.

The fact that you can upgrade the operating system at home with the digital link system means that it is a control box that will stay at the front of the pack for a long time to come as E-Stim Systems continue to improve it over time. It would make an ideal addition to any professional Dominatrix's dungeon equipment or anyone's bedside drawer for that matter and it can be used as a tool to inflict pleasure or pain from afar as well as in person.

Being able to operate it from anywhere with an internet connection means that anyone in a LDR has a kinky way of playing with their partner and bringing some intimacy to their relationship even whilst apart and that's a great feature.

One thing is for sure, this is my go to control box every time I fancy giving myself some hands free orgasms and it will take something seriously impressive to come along to knock it off that spot. If that were to happen though I wouldn't be surprised if it was the next creation from E-Stim Systems that does it.

If after reading this review you decide to buy one for yourself then I do hope that you enjoy it and I would love to hear your thoughts and comments about it in the comments area down below.

I bought my 2B direct from the manufacturer E-Stim Systems and whilst it is available elsewhere I prefer to cut out the middle man and deal with the makers of this extremely powerful e-stim control box.

I am an award winning reviewer and married mother of two who loves getting off with all manner of Sex Toys. I really have a soft spot for Fucking Machines and Sex Machines though (I bet you can guess where that soft spot is). I'm also rather fond of E-Stim or Electrosex as well as kinky BDSM play. I love reviewing all manner of sex toys, adult related products and lubes so join me on my quest for ever kinkier orgasms.
