1-Sided Rechargeable Hand Warmer - White

It's great for a quick warm up. However the battery doesn't last more than 20 minutes on high. So don't look for it to keep you warm. Only to bring some feeling back to your fingers. I work in the cold and have to maintain a well dressed image. I am able to slip this in my pocket and get that quick warm up when neccissary. Overall, it's a welcome relief for my freezing fingers.

With a simple on/off switch and two modes clearly marked, this is easy to use. I love that you can turn it off when not using it, saving the energy, unlike those instant shake-em-up packs you buy in bulk and just throw away. I think the design is very well done, although it does have a little cheaper-feeling plastic shell. The product does exactly what it is advertised to do - heat up. This thing makes a perfect gift for girlfriends, moms and any other special lady in your life. It isn't just for the ladies though, as I have found it useful when camping, hiking or just in my daily train commute on colder days. I highly recommend this product, and while it could be a little cheaper price, it certainly will last me at least a few winters at this pace!
