These things are great! I bought them for camping and they warm up within a minute and last a long time!

I gave these as a gift so idk how they are doing. Seemed good enough when received them and charged them up for my son.

I absolutely love love love these !!!! I happen to work in a foundry it's always hot in there but we had a subzero temperature week and that's when the heat went out in my area ,it was freezing but I ordered these and would keep on in my pocket of my hoodie and would keep one hand warmers while I inspected the parts lol. I would recommend them to anyone !!

These are perfect for pickleball mornings. We keep one in our jacket pocket and hold it when we are not actually playing.They last as long as I have needed them every time , charge fast , and I have let other people try the other one that I don’t use and they said they would be getting a set for themselves —- real 5 star product.

They get very hot! I like the magnets, can be put together to make a single unit for use in a sleeping bag (use lower power setting). My use time is limited to three to five hours of outdoor time, adjusting power settings, no need to have on high all the time. Never ran out of heat. Recharge easily.

2 rechargeable handwarmers for $11, that have 3 settings, and put out some serious heat, and have magnets that allow you to stick them together or on the frig? Can't beat it. Already purchased another set. Never had handwarmers, but am thinking, how did I go this long without them? Makes the cold winter walks better.
