Review on Rechargeable Hand Warmer 8000MAh Power Bank By BRIGENIUS - Double-Sided Heating For Winter, Outdoor Activities, Raynaud'S, And Christmas Gift Ideas by Troy Hamilton

Bought this after seeing a friend with a similar product. Doing a lot of activity outside in the cold, but not wanting to keep track of the disposable hand warmers, I wanted something a bit more "cute" and effective. This was it! It heats up quickly and the fact that I can also use it as a charger for my phone is great. Some other reviews mentioned that some had purchased two so that they could warm both hands at once, this is not necessary but could be depending on how you deal with the cold. However, I usually just transfer it between hands. Of course I did not order it soon enough, but I am prepared for the upcoming cold.whenever it comes (Atlanta).I also like that I can slip it into my back area to help with back pain. I simply pull my belt tight enough to hold it in place and it works perfectly while I am out and unable to use any other product on my back for temporary relief.REALLY worth the price, and it comes with a nice bag to store it when not in use.
