The Product We Never Knew We Were Missing - Today was the first day I used CozyCharge with a full charge. On the lowest setting, it lasted a little over 8 hours. Unbelievable! My wife and I love this product and plan to purchase more as stocking stuffers for the family this year. We live in Michigan, so we know a thing or two about cold weather, and this is the product we never knew we were missing! It's easy to use and fantastic when you're outside and must keep your hands warm. My wife had to stop walking with me in the mornings because of the cold aggravating the arthritis in her hands. This little hand warmer has solved that, and she's now back to walking the neighborhood with me each morning.
