Can't comment on durability yet since only used a few hours but feel solid, battery kinda looks homemade but dang do these gloves work quite well. Riding 40F temps, I have heated grips but my hands can still get cold....not with these. Haven't tested how long battery lasts but these make cold riding 'nice'. Heated grips and these gloves mean I have very comfy hands. Even without the heaters on they are still very warm gloves, definitely only for cold weather for me but amazing for this.

Nice gloves, I just don't think 7 volts heating gets that warm. These were purchased to verify that fact. If you need warm gloves you will need to be plugged into the motorcycle. If you just want a little better then regular gloves these may work for you.

They don't get as warm as I had hoped. Fingers still get cold on 40 degree days going slow
