This is my 2nd Renpho. I've had my other one for 2 1/2 years, and I use it almost daily for my sinus headaches. LOVE it! My first one was expensive, but it can no longer hold a charge, so it was time for a new one. I picked this one because of the remote control. I run mine on silent (HATE the voice!) and I don't always push the correct button to silence it. SO much easier to do with the remote.BUT my remote didn't work! I did EVERY trouble shooting suggestion- checked the battery on my charger check - and it was a good battery (blue light came on) and the blue tooth worked, but the remote did nothing to the device. I reached out to customer service and they told me to return it - and I did an Amazon swap for the same one - and got the new one today - and the battery was dead! Who knows how long it's sat in inventory - Amazon sells a 2 pack for $3, but we had one in our battery drawer and it works!! (YAY!!) I know my daughter is going to steal this when she comes home from college - so I think I'm going to order a 2nd one. It massages right where my head hurts - and the heat is amazing for allergy/headache suffers like me! My husband steals it sometimes, but it's more of a spa-experience for him, for me it's survival from constant migraines!
