Excelente equipo

This item works well and as expected.

My lower back pain has been significantly reduced by this device. I spent many years abusing my back to get into this condition, and have tried numerous remedies to alleviate my suffering, and so far stretching and the use of this TENS machine have been the most successful. The only real issue is that the instructions pretty much assume that I'm a trained and experienced professional physical therapist and programmer. I'm not, so I have had to experiment with different programs and settings until I find what works. Once I found the magic formula, however, I'm practically pain free.If something were to happen to this marvelous machine, I'd buy another immediately.

Funcionan super bien actualizaré de ser necesario

Ok, 1 side is going out. I use this multiple times a day. My first unit was 9v battery, still going strong. This one, the right side operation going in and out. Stays charged but not as good as the battery operating unit.
