OLV Hand Warmers Rechargeable 2 Pack Strong Magnetic 18Hrs Longer Heating Portable Pocket-Sized Hand Warmer 6000mAh USB Hot Heater Birthday Gifts for Men Women Camping,Golf,Hunting,Travel Essentials

These are a very handy tool and work really well to keep cold hands warm. I would certainly buy another set.

Works good pocket size heats fast and perfect temp on them cold morning before the car gets warm

Super warm even on the lowest setting. Love that they stick together with magnets. Fit in my palm while wearing gloves. Great for snowboarding or watching winter soccer games.

I got ten in different colors as Christmas gift. Selected these for the dog on them. Adorable. A frontside and backside. Great gift for dog owners. We are a doggie household. People complain of longevity. One heat setting makes a difference. I keep mine in my back pockets. Works great w jeans, especially w a longer jacket to create a barrier for the heat. Makes a huge difference being outside w the dogs. If I hear anything different I will update the post. They are ten dollars. Idk what some expect. These blow away disposable hand warmers ; in my opinion.

Received my hand warmers today, charged and tested work great. There was no user manual in my box.

I really love them. They are too cute. They came fast. The quality of the product is really good. No issues warm fast. I haven’t really tried them for a long period of time so I can’t really speak about the battery length but from what I’ve tested so far they do get really warm. I would definitely recommend this to friends and family if they’re looking for a good hand warmers and it comes with a cool little case in the box to store easily. I usually use mine for work

These hand warmers get HOT, which I really like. However, they do NOT last 8 hours, or 12 hours, like some commenters said. I charged mine all the way up, the next day I had them on level 3, and within 3 hours they were dead. I am really disappointed that the charge doesn't last that long. I ended up sending these back, I wanted to love them, but honestly one of them would not hold a charge for longer than 30 minutes after being fully charged.

Love this. Hands are always cold and this is a wonderful help.
