I have had great results with this unit

Highly recommend love my tens unit one of the originals very easy to use i had one before works perfectly love super great wish i had found it sooner better sleeping with out taking a lot of aleve or othe pain releaver these are the best to get knots out of your shoulders or just to put anywhere you have tense muscles own several units and have bought them as gifts for the family highly recommend excellent arrived when promised

The unit works very well but of course its not quite like units that pts use but it is effective

This unit works so well and helps so much on my back thank you for a great unit and at such an affordable price
