Review on H E A T Hand Warmer W Primaloft MAX5 by Jeb Moorehead

Bought for a waterfowl trip in North Dakota. I have worked well. Only gave 4 stars because I want it to be warmer. But it does its job well and keeps my hand warm in zero weather. The only other problem is that you have to buy the battery separately from the Otter. But for bird calling in cold weather it was great, I warm my hands up pretty quickly after calling.
