I just received them, they look of good quality and warm up all the way to the fingertips. I will come back soon when the first cold and rains arrive. I hope they last because I really need something like this since my job is 25 kilometers on the road.

I'm coming back to add more.
The battery on full lasts about 1 hour and 10 minutes. After three heavy rains, 40 minutes each time, nothing happened to them and no water got through to my hands. It's amazing. Down to -1 degrees at night, I can say it doesn't keep you completely warm but it doesn't let you freeze either. You drive comfortably and I almost didn't feel cold at all. I don't have hand guards on my bike, so for someone with hand guards, it will do an even better job. It's important to have warm hands. Now I'll see how they hold up over time.

But I really believe I made a purchase where I won't say I threw money away, after three months of daily use. Even though the battery is lithium ion, its performance drops and now it lasts me about half an hour of driving. I hope the battery is available as a spare part
