I haven't used that one, but I tried the "warming mouse" and it is bad. The mouse is not ergonomic and makes my hand really sore within an hour. There's another USB warming mouse warmer in the shape of a blue fish. It's bad, too. Like a piece of junk made in China. I think the one you found at http://www.igmproducts.com is more practical, and the price is right with free shipping and no sales tax. That's a deal. Check out the blogs listed below for more information about the product. Not sure I answered your question, but you may have found the answer to all the Yahoo Answers questions about a cold mouse hand. A blanket makes sense to me! Thanks!!!!
