The fit and quality is fine. Seems similar to other cool/cold winter bike gloves. They DO work in that there is definitely heat in the back of the hand and all 5 fingers. The battery is in the cuff of the glove on the PALM side so there is some extra bulk/pressure in that area. It could be an issue if you have tight cuffs on your winter jacket.

Today's ride was fine, I started the gloves at HIGH for just a minute or two to warm up, then dropped them to MED for the rest of the ride. It was probably not a fair trial, as starting temps were around freezing and although stayed around freezing for the first 2 hours, it was probably not cold enough for a full try. My hands were comfortable (but not warm).

I will have to wait for a really cold day (with temps well below freezing) to see how they hold up. Given how the wind seemed to negate the warmth, I am not certain I will be comfortable in really cold temps but I will withhold judgment until I give them a try.
