Started wearing these for snowmobiling in '20. Great to have the extra heat, kept the fingertips and backs of the hands toasty. Battery life was acceptable as long as they were fully charged before starting a trip. Glove durability is pretty good, heater durability not so much. Started glitching at the beginning of this winter, both gloves shutting off a minute after powering up on a full battery. As of this weekend, neither glove will power up with a full battery. One glove has a faulty connector, it will light up if you wiggle it, but it wont stay on. The other gives a dim red flash when trying to turn on, but wont turn on. A little dissapointing given the cost.
