It gets so hot and will dissolve a blockage in minutes. The 3 temperature settings allow you to change the warmth level. Wish it had lower temp settings but you can work around it by putting it in the bag.

Hand warmers come in clutch for long winter sessions. They're much better and last longer than those disposable hand warmers. I alternate hands between the leash and the hand warmer, which works great!

This product is a total scam! Amazon take this back and refund my money. They let me refund which was really their only redeeming quality.

If you want it on the highest setting it lasts 2 hours. Mine always dies in like 2-3 hours. When hooked up to usb-c charger, nothing happens. Took almost 6 hours to fully charge but battery only lasted about 2.

The temperature is incredibly inconsistent -- on the lowest setting it's sometimes barely warm and sometimes too hot to hold. It is unbearable so i resorted to wrapping them when i used them.
