I hate finding batteries and this thing lasts and lasts off one charge. Disappointed that I can vary the level on different leads and that 2 leads dramatically decreases overall power level.

With all the settings this has, it does not have a continuous setting. Also some settings are very weak and don't provide much stimulation. The rechargeable battery is nice. I prefer the units that use a 9V radio battery and are about the size of a pack of cigarettes.

don't like the fact that there is no, constant setting only different pulses. low power. is what it is.

Nothing

Pads are too sticky.

Pads need to be a little bigger

I wish it had a clip for easier wear while in use.

Works but not very strong

The pads get damaged very quickly even with being super careful. Store great about making it right.

Good
