Poor customer service and return policy
I used this product on the lowest "setting" and only for 3 minutes (recommended to start is 5 mins.)  It hurt my back and caused pain for several days.  Response time to customer service -- takes several days to hear back.  They continue to offer to let me keep it and give me 50% money back.  I don't want it and won't use it again to not risk hurting my back.  They say pain is normal at first, but I'm not taking chances.  BUT so far haven't gotten anyone to let me actually return it.  Emails also don't give a phone number for me to call anyone, so am trying to get a number to speak with someone in management to make an appeal.
