Amazing product!
We love this product! We have had one in our home for two years. We lived it so much we just bought a second one to keep on hand! It has helped my dad on numerous occasions with his back and neck and me with my neck and low back. This US machine with e-stim is the real deal! You don't need overpriced machines. This one is perfect! My medical massage therapist uses it in her office and I had to have one!!
