This electrode is superbly manufactured. The finish is outstanding and it is super easy to disassemble and clean. The substantial size and ridges can make insertion play fun and challenging and the weight reminds your partner that it is there even when no power is being used.
I was surprised that with such a large electrode upper surface when inserted, it still seemed to focus the intensity near the opening muscles giving an intense contraction which can be very pleasurable. I noticed that at least with the power unit I was using that polarity seems to make a big difference. One way stung pretty much, but when flipped by swapping leads with one another it was a comfortable, intense contraction without any of the stinging sensation.
I would be interested to try the 2B unit to see how it comares and hope to aquire it at some point in the future.
I''ll also consider buying the 2.5", 3" and maybe with an aggressive enough play partner in the future the 4" insertables offered by E-Stim Systems.
Excellent product. Keep up the good work.
