This is a review of the Series 1 as well as the 2B. The "stars" are hard to read in my browser, but I selecte 5.
Concerned about the 2B price, I initially bought the Series 1, and used it daily for 1-1/2 years That alone should indicate how satisfied I was with the Series 1. There was a (pleasurable) learning curve. At some point I figured out I could trim the standard surface electrodes to various sizes and shapes, which was a major breakthrough. I'm also getting a lot of mileage with the combination of a surface electrode and an elastic strap. Battery life with the Series 1 was exceptional and I got months of daily use from a single battery.
Seriously concerned about having a backup should something terrible happen to my Seiries 1 (but I want to emphasize that I have had NO problems with either unit) and leave a sudden emptiness in my life, I ordered a 2B. The greatly expanded adjustability makes it several times more pleasurable than my Series 1. I wouldn't say my time with the Series 1 was wasted, and would definitely recommend to anyone with the same initial concerns I had, but the 2B is the real thing :-) The audio CD is something else, and putting the CD on my iPhone really simplifies use. Setup with 2 channels is pretty cluttered (then add the audio cable...), but single channel use is still very gratifying, and is how I generally am using the 2B. (I guess I grew up using one hand, while the other held the pictures ;-) I'm definitely looking forward to trying the Triphase cable as a way control "clutter", though.
I strongly recommend getting spare cables. The quality is excellent, but they do wear out, and you don't want to be caught short. I've also gotten a lot mileage by renewing my surface pads with the Tac Gel. Battery life with the 2B seems significantly less than with the Series 1, but then my time spent with the Series 1 has gone up ;-)
If I were designing the 2C, I'd add some memory and explore loading the CD and other programs directly into the unit. I'd also try to figure out a way to add a 2nd adjustment control. Finally, IOs or Android versions of the Commander software (which I haven't tried) would be awesome. (Has anyone tried making tracks with something like GarageBand?)
Customer service is great, and overseas delivery times have have dramatically improved with the switch to DHL.
I'll draw a final analogy by comparing my E-Stim units with past girlfriends, all of whom I love dearly. (The girlfriends, of course). My girlfriends didn't necessarily give perfect handjobs, and required some respectful training, but was it ever fun.
It is a wonderful little box of tricks. I am a beginner and although it was a little difficult getting used to and results were sometimes mixed, it is possible to achieve the desired result. The range of programs is great; not all of them work for me, though I understand that there are a number of different factors involved in stim & HFO.
I give it a 3 star (why do what I see above are all 5 stars?). I'm sorry to say that at this point I'm not really too impressed with the 2B. I've been using the ET-312 for a few years and find that it has more variety of sensations and is far easier to use than your 2B. I'm still exploring your unit so my opinion still may change, but for the time being I'm using my ET-312 most of my play.
The other problem associated with your 2B is the cost factor. By the time I paid shipping from England, delivery charge from DHL delivery, and Customs fees my final bill was around $500 - much more than I had expected from your web site. Sorry to be negative, but I'm just not impressed at this point. Would I recommend friends to purchase the 2B? Probably not.
On the positive side, I gave a friend information on your bi-polar tit clamps. Both he and I have used them and find them quite good.
[ED: We're sorry to hear you're not entirely satisfied with your purchase, but we appreciate that you're not giving up on the 2B yet, and we appreciate your feedback. It might take a while to get used to after using another unit for so long. The 2B and ET-312 are different units, and each has a different style of play.
One of the benefits of the 2B is its upgrade-ability, and we are always working on improving its programs. The cost issue with US shipping is something we're working on. At the moment we ship directly from the UK, and unfortunately customs will occasionally attach their fees. We are working towards having distributers based in the US.]
Just spent a very enjoyable evening playing with my sub and our 2b. I love the different modes and the screen works really well when we turn the lights down. 5/5
I've had my 2B for just over a week now and OMG. This is one fantastic piece of kit. I owned a basic model 2 a while ago but this is awesome. HFO is the norm rather than the exception. The 2B is particularly good with the mains adapter as the model I had before drained the twin batteries within a short space of time leaving me feeling disappointed. I used the audio CD for the first time today and was blown away. Thanks E-Stim Systems.
