Just got my first E-stim device. Had been using a tens unit. Wow, what a difference! The pebble has been wonder so far.
I can see purchasing a 2b in my future.

These really is a big difference between a Tens and any of the boxes from E-stim systems.
I have ended up collecting a Helix, Series 1, Pebble, and a 2B. Because they all have a different feel even on the same modes and settings.
If I had to live with just one box I would likely choose the 2B however the Helix is worth its price just for the tease mode which is nothing
like the tease on the pebble and would likely be my next choice.
