Worst buy ever
Terrible product. It fit my husband's back so nicely that even though it malfunctioned after only 2 one-half hour sessions on 2 separate days, I bought another, thinking the first might have just been a lemon. The second one purchased 10 days later was even worse. He used it for 20 minutes; it stopped. Replaced brand new Energizer batteries; would not start. Replaced with brand new Duracell batteries; would not work. All batteries fine in other products. Took it apart to try check wiring. We can fix many simple wiring problems with other devices, but not these. Did not return as we had tried to repair...so out $40.00. Saw 2 other reviews with same problem. Don't buy.
