strong stimulation signal
I had a spinal cord infection, my nerves are damaged, so I need a stronger signal to stimulate my muscles. This has 30 levels, and it is strong enough to stimulate my muscles.<br />I am actually impressed, I tried 2 other devices, this is a lot better, and a lot cheaper. Even if it doesn't last (it came with 2-year warranty btw), it worth the price.
