This controller is a basic, e-stim controller with a few settings that can be sped up or I can also call it a preprogrammed mixture of the settings. The only drawback with how the controller functions is that despite having two channels, only one output works at a time. The left output will override the right so that the device in the right only receives power once the left plug is removed. Otherwise, the controller is basic and simple to operate. Receiving stimulation from the device can be more difficult though. Unfortunately, there is not a lot of documentation on how to use it, for instance, where to place the pads for stimulation, what it should/shouldn't feel like, troubleshooting for no stimulation from the device, FAQs, etc. for this set or the other e-play devices.

The gel pads feel cool, are easily removable and replaceable, and stay in place. If placed in just the right spot, this device can make a muscle involuntarily contract. If the pad is not placed in just the right spot, there will be no stimulation at all. If one of the gel pads is not making good skin contact or if one pad is attached and the other is barely touching the skin, a stinging, burning sensation will be felt from the pad with poor contact.

I remember exercise products that would electronically stimulate a muscle contraction so someone could workout while watching TV or driving to work. Gimmicky.. This device can cause a similar muscle response if the pads are properly placed. And similarly, my e-stim experience has felt gimmicky as I got the controller for the e-play tingle probe, a flop for me. I was hoping for direct, sexual stimulation, but have only achieved stimulation of hands and some arm and leg muscles with these pads. I can't recommend e-stim at all, but if you know you're into it, this set is ok as a basic entry device. If you're really into e-stim, you'd probably like something less basic instead.
