My hands have been cold for years, no matter what type of glove or mitten I have used. I received these Mitts for Xmas and can honestly say, my hands and fingers are very pleased. We have experienced windchills of -28 -30 this winter and had no issues whether out shovelling or for a walk.. Having the Flip top, makes reaching into ones pocket or answering a cell so much more comfortable. I would highly recommend these Heated Flip Top Mittens to anyone looking.
