The gloves worked very well @ < 50 degrees on low while riding my motorcycle with grip heaters on low. The glove heats on the top of the hand and at the fingers which is what is needed when riding a motorcycle. High was way too warm and I had to put them on low. The fresh batteries lasted 3 hours and still have over 1.5 volts each so they will probably last another 3 hours of riding. The gloves fit correctly, which means that they fit slightly tight. All heated gear has to fit kind of tight or you will never get enough heat to your body. I was very impressed with the fingertip heat, which I did not expect after reading other reviews. People are probably buying gloves that are too large; remember to purchase gear that fits kind of tight. My regular riding gloves are large but these were ordered in medium because they are heated. I tested the current draw and it was (1 watt) 0.75 amps on high and (0.5 watt) 0.33 amps on low so I don't think they will work well below about 35 degrees on a motorcycle - I'll find out if that is true in two months. Excellent value for the money. Remember fresh batteries, not the ones left over from 3 or 4 years ago!
