"Great little unit! Easy to use. Definitely works to relieve my complex knee surgery pain & helping re activate my quad! Seems well made, lightweight but durable! Lots of extra pads included. I’ve used it a bunch and haven’t charged it yet. It has found a rightful place in my gym bag! I definitely will use it even after I’m out of rehab! I would have given five stars but there is no description of what each program does so you kind of have to test each one out and take note of it. Other than that, it’s a wonderful little unit. I’ve gotten so many compliments from everyone at my physical therapist office!"

Did absolutely buy me short periods of reduced acute radiculopathy pain pre-surgery for disc herniation/extrusion.Didn't use the muscle stimulation modes, only TENS and followed the manual.Battery lasts surprisingly long, intuitive except for the modes initially but manual is easy to follow.sandi
Works just like advertised, read directions and start off low and work yourself up.
