I have had several of these do not but they last less than a week this last one I had lasts 2 min way overpriced and its crap I also had some that caused burn holes and it damaged my 2 throw blankets I believe it is a fire hazard and needs re made and re evualted otherwise they need to make a lifetime replacement i believe there's issues in wiring somewhere and they have nothing to protect against fires or overheating. User's recommendation: Do not purchase.
