Picked up these liners to see if they would work in conjunction with premium gloves and they do. Plus they were open boxed so managed to save a bit too. They warm up quickly and with both I hope to get by on low setting with each but it has not been cold enough to test this yet. My only issue is S/M seems a bit too small for me though I am a solid M in the gloves. If they have separated them out and kept each as a different size like the gloves would probably be a better fit.

The glove liners don't get warm enough and battery don't last long. I need something better.

These truly are only heated liners. I had hoped they would get warm enough to suffice as lightweight gloves on mild days, but in the mid 30’s they only keep the chill off. Using them as liners can be a bit difficult. The bulk of the gauntlet with the batteries installed is uncomfortable under other gloves. By the time you upsize the outer gloves to fit over these, dexterity is gone and overall become bulky. Sometimes the battery packs shift to an uncomfortable position at the back of the wrist. All in all, they are as advertised. I’ll keep them around for light duty or recreational use, but in the end wish I had bought a heavier pair of heated gloves and not just liners. Overall, Not quite what I needed, but that’s not the products fault. They might be great for someone else.

I have poor circulation in my left hand. These heated glove liners are the perfect way to keep my fingers and hands warm and flexible.

I use them when riding my ebike with temperatures in the 30s and 40s. I use them at the warmest setting and they don’t get very warm. I have Reynaud’s syndrome and my hands get very cold. Also, the batteries are pretty much dead after about an hour of use. I bought size S/M which fit my hands fine but the gauntlet part of the gloves are very tight especially with the batteries in the pockets. This has caused one of the zippers to open up and it can’t be zipped up again.

Gloves are nice but batteries don’t last long at all. Have to order another set of batteries so I change them out when they die.

Gloves are great, fit very snug but not uncomfortably, and almost not noticed under another pair.

5 Stars. After multiple hours of use and a few charges, I can say they work well, like they should. I was a little concerned as I am below average in height, but the measurements indicated that I just barely fit into a L/XL. They fit. They are stretchy with a lycra like material. The first time I tried them, one of the batteries didn't work. After making sure it was recharged fully, it works now without any issue. The buttons to change heat settings are easy to use while riding. I have used these for motorcycle riding. I use my heavier cycle gloves over them. They fit, but are bit tighter than I wish, but not enough to stop me from using them. These warmers are the difference in a bearable ride and comfortable and fun ride for rides in 30s F. In fact after my 30 minute commute I let the office assistant wear them. She loves them to warm her hands in our underheated office. The buttons to change heat settings display well and are easy to use while riding. They fit over my jacket sleeves. They charge fast, and come with a nice dual charger. I wish I got these for all those night games of soccer and football watching from the cold stands.
