Bought these to go under my regular gloves which I've had forever, they slid right in and since using them my fingers are no longer cold!

These glove liners work! They keep my fingers warm, and will warm the up fast if I put them on after my fingers get cold.

Glove seems nice, fingers run way too short. Used sizing chart provided, glove fit hand well, fingers were about 1/2" too short and I don't have long fingers. Typical gloves have fingers longer than me.

I kept my gloves on the second setting (green) while working outside for a continous 7 hours. The lowest setting would last for eight hours.The only time the gloves got noticeably warm was on high (red, lasts 2.5 hours). My hands were still cold most of the time. So I am not a fan of these. Gloves are not managable with the app. I waited past the 30 day return period so I will sell through a local app.

I ordered these based on another person's review that they worked really well for horseback riding in Connecticut in the winter. I didn't believe that they would be able to keep up, but as long as it's not breezy, they are awesome, even in the low 30s. They provide dexterity and having 4 heat settings is really nice. I also wear them under a larger pair of gloves for barn chores and they were a finger saver last winter when it was really cold. The first pair are fine, but I wanted an additional set of batteries and it didn't pay to buy them separately. I gave 5 stars and not 4 because they ARE liners and there is only so much that can be expected of a pair of liners.

I have used these heater glove only once for a 10 mile snowshoe hike on a cold day when temps started at 8F. They were great in helping to warm my hands immediately after putting on my snow shoes bare handed. Trying to put the snowshoes on while wearing the gloves would be more difficult due to the binding system on the shoes. Personally I do tend to warm up fast during a vigorous hike and start sweating as well. As a result my hands also tend to begin sweating, which is where my problem is. Once I'm warmed up I adjust clothing layers to cool down, but trying to do the same for my hands is not as easy. So if the gloves become damp from sweat or snow they will get colder if I need to remove them for any reason. Once wet the cold air will make them colder and then trying to heat one's hands is impossible. They worked fine until they became damp, so you MUST keep them dry to work for a long trip. Now that I know this I'll try to make sure to keep them dry if possible. In fairness, my hiking partner has used similar heater gloves and she does not sweat like I do and has had no problem keeping her gloves dry. Clearly the problem is personal to each individual. In the meantime I'll try using them at home when clearing snow around my house and driveway.
