Are you looking to try electrical stimulation at a reasonable rate? Try this e-Stim controller where you can get multiple accessories for a variety of new stimulation. It isn't a Tens unit or a violet wand, but it isn't as expensive either. Watch this video as Dan walks through the process.

This isn't a toy that is used directly on the body. It is a control unit for other toys and therefore is irrelevant. That being said it is a solid plastic device and a place for batteries.

This is an inexpensive product so don't expect it to last 20 years (maybe a couple). It is pretty simple to use. The buttons are a bit hard to read if you are in the dark or older and need reading glasses, but once you get familiar with it that shouldn't be too much of a problem.

For the price it comes at this is a pretty great little product. There are technically an unlimited number of choices for the controls. First you have the on/off button then 4 different buttons for different pulse choices. Finally, you can augment that with varying the intensity and the power. Overall, this is not a very strong toy, but for someone just trying it out it could be fun.

I wouldn't get this wet and you will need to replace the batteries periodically. Wiping with a damp cloth can catch any lube or other substances you get on the casing.

The packaging is minimal: a cardboard box and plastic wrap. I had no directions, but you can get those online.

Unfortunately, this did not work with the e-rings that I already had. I was looking forward to a bit more power from this device than the controller that came with the e-rings. I like more intensity in my electricity toys.
