The gloves are not very warm. Fingers freeze in them.
The description has not certain information about the size, so it is very easy to make mistake. Seller will not help you, if you follow the description and chosen size will not fit you. Also, information about working (heating) time is not accurate. Maximum (at -15 *C) is about 1-1,5 hours of work. So be careful, 3-6 hours is not true.
