FANTASTIC COLDFIGHTER!!!
I received this as a gift for Christmas, & as a valet working outdoors in New Jersey winters, this thing is a real game-changer! It looks & fit great under my coat(s), it heats up & down quickly, it helps with my backaches, it's washable - the list of likes go on & on. The battery charges up fast & lasts for my whole 6-hour shift, where I start out in the white zone (100°) & then increase it to blue (115°) & finally red (130°) so as the sun sets, I can use the additional warmth. It's well-made, & with a one months' trial weartime under my belt already I know I have a wearable tool that helps me get through the long, cold afternoons & early evenings. Recommended highly!
