Output B stopped working after about 20 uses. Was happy with the unit up until then.

I like the stimulation, but it's weak. I was hoping it increased higher than 20. I may have to return it, I have a high tolerance. But I think it's a good device

I would give it a 5 if this came with a belt clip holster. Other units that cost 1/2 and work just as good, include a holster. Other than this, this device works fine, so far.
