Gerbing Core Heat 7V Back Wrap 5 5 6 6
Wanted heat on may back - got heat on my back! A lot of competitive products on the market to choose from but I think I got the best choice for me! Looks and works as advertised! March 2, 2015
Perfect if you work outdoors. I am an electrician and on my first day out in the cold this year, I wore the Core wrap under 3 layers of clothing and I was warm. My problem is poor circulation in my fingers and when your hands get cold, your efficiency is compromised. The Core wrap kept my core warm which kept my fingers and toes warm. I recommend this product for anyone who works outdoors in cold temperatures. Be sure to pick up an extra battery so that you can use this product all day long. I seem to stay warm enough by operating the Core wrap at 25%. November 24, 2014
Awesome Great for those especially tired days. I am a contractor and that comes with a lot of demand on the back. This heated back wrap soothes it every time. Worth the money! November 25, 2013
I am so happy that was able to find so amazing Back Wrap. I am so happy that was able to find so amazing Back Wrap. My husband have big problem with back after injury during last 20 years. All these years he used only Ice-Heat patches and Wraps, and it was taking from 5 days to couple weeks before he began feel batter after using patches and wraps. These patches and wraps are not comfortable, not enough strong and also after several days of using you can get problem with your skin. After my husband retired 6 months ago and we began travel more, his back pain became much strong, because of or driving long distance, or because of sitting in the planes. Because of this I decided to look for something more useable and stronger then Ice-Heat patches and wraps. The only kind of stuff I was looking for was Gerbing's Core Heat Back Wrap. After long time researching, I found that there is not possible to find something similar to this back wrap. I liked everything what I was reading in the description of this product before purchasing, but in same time I afraid that it also won’t work for my husband. But I didn’t have a choice, because how I said, it was the only kind of product you will be able to find. But now I want to say that it is amazing product! It works for 100%! So easy to use, battery doesn’t need to be charging during long time. Adjustable heat works in same temperature as set up. My husband is so happy to be free from his pain. He uses it home and also we don’t leave for long time from house without this Heat Back Wrap. It is number 1 in our travel list. I present it for my husband’s Birthday on December 3 and it was enough time to get that it is a very good product. My husband is still saying that it is the best present he got for his Birthday! There is only one succession: to sale it with some bag to be able to keep it clean when people don’t use it and be able to use this bag for traveling: to keep together Wrap, battery and charger. Thank you very much for good quality product. January 5, 2012
What a great product! Great product. I bought it to relieve my back problems. It works great. Well made and very functional. December 26, 2011
Excellent Backwarmer This product surpassed all my expectations. I didn't think a 7v system could produce as much heat for as long as this product does. I warmed it up on high and then put it on the lowest setting for hours of soothing warmth. If I wear a vest over the product it works even better. I also tested the product in sub zero temperatures and it kept my lower back toasty warm (although it was necessary to move up the setting a little). It is not a substitute for a heated vest or jacket, as my upper back got cold; but it did extend the comfort range of other clothing. December 12, 2011

Robert C: I have two deteriorating discs in my back (L-4, L-5), and experience constant pain. I purchased this to function as heat therapy. It appears that the heat will last much longer than a microwave heated pad, and is more mobile than a corded device. Nov 21, 2014
"" ": I picked this because addition heat in cool weather and better back support. Also the reviews about the back wrap answered questions that I had about the product. I bought at RevZilla because of FREE shipping, Zilla cash rewards and THEY PAY THE TAX. Great place to shop by way of internet and at the store. Better then other so called discounted stores Ha Ha.
