I love the gloves. Unfortunately, I got the wrong size. I did not want the hassle of having to do an exchange online and kept putting it off and then when I went to do it, my return window had run out. I normally wear a women's size medium glove. Since these gloves are unisex, I ordered a size small. The gloves were still about an inch too long in the fingers. The gloves keep my hands warm and are comfortable, but since they are too large, I have to take them off anytime I need to pick up or manipulate something. The batteries are nice because they are flat and not bulkie compared to other heated clothing batteries that I have encountered. So, my advice to women who wear a medium glove, is to order an extra-small in this glove. The manufacturer should come up with an accurate sizing chart that can be used.

I have buerger's disease and lost my lower left leg in the mid nineties from it; this disease cause circulation issues. The disease has caused me lots of problems in the other leg and both arms sense then. The winter before last was a very cold winter. I live near Boise, Idaho. I had a lot of problems and pain that winter in my left hand, the doctors thought Iwas going to loose my hand, fortunately I did not yet. During the summer I had looked for some heated gloves to and chose these. Was looking for ones that heated the fingers and able to afford. We have had a very mild winter and I did not have as much outside activity as normal with the covid19 so I have not fully tested them. There are suppose to heat to 150 degrees; I am not sure they get that warm but they have help. When I can afford it I do need to get more batteries and charger because when I did use them on a cold day the batteries went dead. Another thing is the charger will only work on 120 volts. It will not charge on 12 volts (car). That part is the biggest complaint I have at this time.
What they need to do is put an affordable package together with home/car charger and 2 extra batteries; like power tools do. Also better finger heat would be very good as well.

I've used these gloves over a dozen times, on my motorcycle, in temps down to 38 degrees, riding 55 - 65 MPH. I don't know that I would be able to use them in much lower temps. At 38 degrees, with the gloves on high, my hands never got cold, but I could feel "cool spots" in the glove. So I'd say they definitely worked as advertised. My only beef is the fitting. The finger lengths seems odd to me. The glove fits my hands perfectly through the width of my palm, but the finger length on some of the fingers and thumbs are a bit too long. Not too long to impede my operating the bike, but long enough to be slightly annoying. So overall, if these gloves fit your budget, you really can't go wrong. I would buy them again in a heartbeat.

Overall, glove quality is very good. I followed the sizing chart provided in the listing, and ordered the size as recommended. I also had a previous pair of heated gloves that I used for sizing comparison (both of which were the same size). When I tried them on they fit very snug and almost too short in the fingers. Return was hassle free and I immediately ordered the next size larger. Those fit very well.

I purchased these for my husband for Christmas. He suffers from nerve problems in his hands that cause extreme sensitivity to cold. He's worn these a number of times now when snow blowing and has been really happy with the fact that they keep not just his hands but his finger tips warm without any problem at all. Highly recommend them to anyone that has Renaud's or problems in terms of cold sensitivity. Extremely good gloves.

Update:

My husband has had these now almost a year and they are still going strong. Highly recommend them. He has not had one problem with them and it happy that the batteries are so easily accessible for charging. The gloves are just awesome.

UPDATE: 2 years

My husband has had these gloves now for 2 years and they still perform as if brand new. He's have absolutely no problem with them at all. The batteries charge great and the heating elements in the gloves are still as strong as they were when they were new. The heating of the gloves is so good that at time my husband needs to take them off because they actually get to hot.

UPDATE
My husband is going into his 5th winter with these gloves and they are still going strong. He has not had one problem with them since I gave them to him for Christmas in 2018. And the batteries are the original batteries that came with the gloves. They still have no problem holding a charge. He couldn't be any happier with them. Assuming they have not changed anything in terms of materials and/or design, I would highly recommend them.
