These gloves are BRILLIANT when they work. And they do work most of the time. I took them skiing this year. If you are planning to go skiing or snowboarding then they are great. On high heat they will last about 2 hours. Medium heat around 4 hours, and low heat around 6.
High heat is the best and I found this most beneficial in short bursts during chair lifts or even gondola lifts up the mountain, when you are inactive.
The rest of the time the gloves were really good in insulating my cold hands anyway.
