Some time back there was discussion of tens units. So me thought they were $750.00 I don't know where those were made, I just bought one for <300.00 and then later found out that the ones I paid $500.00 are now 266.95. If you want the brand names and a telephone (800) where someone will tell you if they sell that brand where you live. They will also tell you they cannot sell directly to the public, I have no finicial interest in these companies, just wanted to stop hurting. I have worn 2 at a time- but the 2 just quit. I was told and believe that it is close to impossible ( if not impossible to repair one) If some out there knows of any way to have them repaired l or want to know where I got them write me off list..
