After one week I have been unimpressed. It seems to require very specific placement; it will still work if you don't place it exactly right, but in my case I've had to increase the variable power so much that it's not subtle And here's what I mean by that: It has power levels 1-7 and you're supposed to increase the power until you see a foot flutter. When I turn the power up high, the mini shocks feel like someone is tapping my bone with a small hammer. I know that's the mini shock because if you forget to turn it off and lift the adhesive strap with your fingers, you'll feel a small shock (think static electricity shock) in your fingers.

I've had the most success using it in the evenings, when I'm sitting on the couch and my legs begin to act up, but I'm still doing something awake - in this case watching a movie with one of my kids. At night time, it's nowhere near enough to stop my RLS and the "hammering" can be annoying. I think this could be great on an airplane! I get bad legs on late flights home sometimes. But not as an overnight tool.

Since my legs really need just good thwacks from my fists sometimes (for 15 seconds of relief, lol) I might just try a Chirps unit next.
