I was given a Relief Wrap for Christmas. I deal with chronic neck and shoulder pain. I find heat soothing. However, the power cord between the wrap and the controller is turning black, and now the controller itself is discoloring due to overheating. Mine was purchased at Bed Bath & Beyond for Christmas 2017 and today is March 6, 2018, barely 2 and 1/2 months of use. This item is also approved by Underwriters Laboratories as being safe? All the reviews seem to center around defective controllers. I could barely handle mine because it was so hot. I unplugged it and am bringing it back to Bed Bath & Beyond! Total safety issue.
Bottom Line: No, I would not recommend this to a friend
