Review: Absolute best heating pad in the world - I have a very old version of the Thermophore I picked up at a garage sale for $5. I love it. I am have serious issues with my back that causes pain down my whole right leg. Heat helps it a lot. So I needed another heating pad. I tried others, then found out the Thermophore was still being made. I quickly ponied up the $70, and boy it's worth every penny of that. Pad has some heft without being too heavy like the weighted heating pad I tried and returned. It gets hot- like feels like getting burnt hot if on high and against your skin. But that's good. You can put on top of blanket instead of fussing to get it under- which is ideal if moving causes back / leg pain. Love the updated controls. Unlike my old version, this one has 3 heat sets with time making it easier to use. Old one has a switch you need to hold to have the pad work. New one is bit narrower but is longer which is handy. The old one is from 1970s and still works fine I'll definitely buy another if I needed it but most likely I'll have to put these in my will. They are that well made.
Review: Ahhhhh, so very comforting - If you have aches and pains this is a wonderful product that is large enough to either wrap around your legs and/or lie flat and cover most of your back. The on/off switch is easy to use, plus the newly designed push button system makes it easy to go from light, medium or hot settings. Thermophore has always made a great product that gives off moist heat and this version automatically shuts off after a few minutes. You can now take a nap with it on your body without worrying that it would burn you if you fall asleep.

### ⭐⭐⭐⭐⭐ Absolute best heating pad in the world

### ⭐⭐⭐⭐⭐ Soothing & Healing ~ But Very Hot ~ Can Get Up To 160 Degrees
*by M***R on March 5, 2014*

The pad is gently warm in one minute, and reaches maximum heat within 3 to 5 minutes. With the pad laying on top the body it gets very warm, the pause and/or off button turns off heat at any point. The instructions say to not lay on the pad. When I tried laying my leg on top the pad, the captured heat was intensely uncomfortable. Curious how hot? > 1. I laid a candy thermometer between pad & body = 123 degrees. > 2. Pad wrapped around thermometer = 140 degrees. (Customer service says it can get up to 160 degrees if trapping heat by laying on it) > 3. Pad wrapped around thermometer, with blanket on top = 162 degrees. The pads moist heat penetrates tissue and joints which is very effective in giving remarkable relief. I purchased this to help with a knee injury and experienced improved mobility and less aches and pain starting from the first time of use. (Two 20 minute sessions) I felt the treatments alleviated soreness and jump started a healing process, because the area was still dramatically more limber the next day. OVERVIEW OF PRODUCT ~ > 1. The 100% cotton cover is specifically designed to absorb moisture from the atmosphere between uses and release the moisture during heat activation. The moisture is obviously present because skin or clothing becomes slightly damp. > 2. Auto Switch ~ Small red light stays continually on to show it's plugged in properly ~ Aids finding switch in the dark. Switch has a bar of four blinking lights ~ one bar per 5 minutes. A light becomes solid with each 5 minutes used. Automatically turns off in 20 minutes. (Much nicer to use then Thermophore's 'Classic switch' (in their red boxes) which must be continually held down to heat) There's no control of heat settings, such as high - med - low. And no way to have it stay on continually. I phoned customer service to ask them why the product is designed this way, they said ~ safety reasons. Because it gets very warm/hot to provide good therapy, as hot as 160 degrees if covered or laid on top of, it can be harmful to a person ~ burns. And dangerous ~ electric shock and/or fire. > 3. Large pad (14" x 27") is weighted construction so it drapes better over the body. Pad with cover weights 2.12 lb. > 4. Latex free ~ On the box it says "contains no chemicals". Instructions booklet under warnings says "This product contains chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm". > 5. Made in U.S.A. Two year warranty from date of purchase, but if don't have receipt, 3 year warranty from date of manufacturing. Costumer service says they don't use reconditioned products, all replacements are new. A sticker on the end of the box contains the 3 digit model #, the middle 4 numbers are the manufacturing date. The first two # stand for which of 52 weeks of the year ~ the last two stand for the year. So 5113 = Dec 2013. This is an outstanding product in both high end quality and effectiveness. Suggested ~ effective uses for this moist heat, heating pad ~ arthritis pain ~ back pain ~ fibromyalgia ~ TMJ ~ muscle spasms ~ chronic pain ~ and speeding the recovery of injury's. I found this #155 at out local medical supply store for $102.95 plus tax. I was delighted to purchase it on Amazon for less ($63.88 & free S&H)
