This is seriously THE BEST heating pad I have ever used. I LOVE it. It heats up so quickly, the highest setting is so hot it is really great for aches and pain. The length is amazing, it can easily be wrapped around arms and reach the length of most backs. Best of all, Sunbeam customer care is amazing. My XL Express heating pad stopped working on Thursday last week. I got online Friday morning and used the Sunbeam website's instant chat. I explained what happened and after a short (5 min) conversation, the issue was resolved. Customer care had put in request for a replacement (didn't have to send proof of purchase, proof that it was broken, or send my old one back) and by Thursday (less than a week after contacting customer service) there was a brand new replacement at my door step. Cannot recommend enough!
