These gloves are awesome. They work well when I'm in freezing temperatures. I leave my gloves on the lowest temperature to save battery life and I am still warm in freezing temperatures without using the highest heat settings.
These are well made and comfortable. We have hard winters in NY state and I needed something that would keep my hands warm. Thses seem to do the trick.
Satisfied with purchase. I work in 30 degree environment where other gloves did not offer the flexibility and warmth.
