These gloves have performed excellent on long distance mc rides. Disclaimer: I do not live in a cold weather climate, SE AZ.I ordered these gloves and they came on time (the next day). I charged the batteries, and took my dog on a long walk with the temperature being 4 degrees F. I wear a small, and the gloves fit pretty well. I have short fingers, and they gloves were slightly too long, but it wasn't a problem. On my walk, I didn't feel that the gloves were providing heat, but my hands weren't cold. When I got inside, I found that the gloves were providing a lot of heat.The only concern I have is that the tips of my index fingers, particularly on the left hand, does get cold. I wonder if it is because of the touch screen feature at the end of the finger (which works for some things, but not for others. this may be a result of the glove being slightly too long for my fingers). I wanted to contact the seller, but couldn't see how to do that.On the positive side, I've had other heated gloves, and these are by far the thinnest (and I ordered the thicker glove). This is a real benefit in terms of doing anything that requires dexterity while wearing them. They are comfortable and quite warm. I would recommend them to anyone searching for a good heated glove despite the concerns outlined above.I ordered XL size. FIT MUCH TOO SMALLI have small hands for a man my size (XL) but ordered up for more room. Gloves fit like a med certainly not accurate to size chart.MY BAD Failed to read Amazon ad carefully. It does limit returns to damage/defectOn the positive side the gloves do get hot quickly and fingertips are quite warmBatteries last for hours. Kept my hands warm.Gloves are amazing!!! I use them when I ride my escooter going 50mph and I don't feel no cold at all!! Matter of fact I have to put them on the lowest setting. Great buy, can't go wrong. Also they are nice and thin.These gloves are great. I've been using them when I walk my dog on very cold days and it makes the experience much more tolerable! Would recommend!They go a pretty good job heating your hands, but my fingers are what tends to get cold and they really don't work for that. It did last several hours on medium heat, but I did not feel they were worth the price and returned them.Fast charging. Kept my hands warm during a 75 minute walk in 25 degree weather.
