It has an unusually long thumb (which also has no heat on the tip!). Otherwise the heat is very good - provided it's covered with a good glove or mit. On its own the insulation is thin and it cools off very quickly. I don't think there are heating elements on the front of the hand.Note that the power button is different than in the photo - it uses the now ubiquitous blocky silicone button that changes colors. But this one has 5 (!) levels in a veritable rainbow of colors.Unless you have a long, hot thumb, there are better alternatives out there, like the even thinner Venture Heat Glove Liner, or for people who need extreme heat, the 12V MotionHeat Liner. If you're considering a fully insulated heated glove, check out the excellent Savior Glove (not to be confused with their liner, which is terrible).I have Raynauds...these gloves work well but I still miss my Alphaheat battery heated glove liners.I have poor circulation and a touch of Raynaud's. These gloves work as stand alone gloves from about 45° to 60° Anything colder requires them to be used as liners. They do work.?Didn't keep my hands warm. Seemed to lose all the heat that was produced. Might be great for others or other conditions, but didn't work for me.Disappointed in the follow through from the company! Ordered gloves and they didn’t fit. I tried to exchange not asking for my money back just an exchange for a larger size and I was told it was not returnable. Customer service was lackluster at best and now I have a pair of expensive gloves that don’t fit and I’m buying another pair for hunting season.These are awesome for any outdoor activity in cool/cold weather. Great quality and well thought out design. Best that I have found for motorcycle use down to low 20’s without the cumbersome wiring hook up. I loved my Gerbings until I got these. I haden’t used the Gerbings since! The battery life is impressive, but it’s great that they also have extra batteries available so no worries if a quick jaunt turns into a spontaneous all day ride.I purchased a pair of their gloves. One battery did not work from the start. Customer service replaced.
