Two in box barely got warm.............not like others have.
on August 23, 2016
I have used these for years and loved them. It is hard to find the ones for knees locally anymore. I ordered 3 packs for that reason. I just tried one box and cannot get any heat from them. I don't know if these were flawed; but, I am having upcoming surgery and counted on these to help...NOT...do not heat up past barely warm. I am getting a refund in case these were , as I said, flawed. I will order again if I can't find them locally because I normally do love them. Thank you for your help AMAZON!
