Awesome for RA...but
Used it twice and it really helped relieve the pain of my RA. However there was no washable lining included as stated on ad. So i just used cheap gloves from walmart and it was fine to protect my hands from burning. When I was preparing to use it  a third time, I turned it on waiting to heat up and the plastic melted together. So unfortunately, i had to return it but will buy another. Overall i love the size, bc I have petite hands, it covers half my arm helping with the painful RA in my wrists. The only complaint if it didn't melt on me, is I wish it would close the opening keeping the heat in.
