They work very well and have lots of modes for heat. It is very easy to use and you can take them anywhere you want. i personally use them while I game because my hands get very cold. after rounds I turn them on and they are at the max heat in under 2 minutes. The size is perfect and the colors are great. This is a great product and works wonders on your hands. And, you can use them for more than your hands as well.

This product is really good. They charge fast, keep in mind you need to make sure the charger you use is a good one, to verify, one of the blue lights will turn green to indicate fast charging as label in the instructions (look at last picture for reference). I feel like most of the other reviews used a slower charging setup. I use my Google pixel 7 charger which is USB-C to USB-C. You can also use the cables provided but you need a good power box. The heat it provides is excellent, I live in Chicago so the weather is cold and these work great. I really like the fact that it can be on the highest heat setting and once I turn them off it takes seconds to cool down, pretty neat feature so I can store them away without risking heat damage to anything. I also like the ability to use these as a power bank, Great feature. I like that it also comes with 2 charging cables and a carry bag. Overall really solid product, great heat output with multiple heat setting and great additional features and it's not heavy. I would buy again. I recommend this product.Now on the downside....First in foremost the instructions are terrible and can be updated. This version of handwarmers which are the gamer edition don't come with the dual USB-C, meaning I have to use 2 different chargers or charge one at a time which is just inconvenient.

Great handwarmers, and could be used as a battery bank.They can get overly warm if you're not paying attention to the settings.

I play rec football year round, including winter, and keeping my hands warm so I can actually catch a ball is pretty key. On really cold days, vinyl gloves under the receiver gloves just isn't enough. One of my teammates got these and showed me his set - in 20 degree (F) weather with two layers of gloves on, they immediately warmed up my hands. So after the game I ordered my own set. I had a chance to use them last week and yeah, definitely keep the cold at bay while I was holding them.I didn't give all five stars for a few reasons. First thing I noticed is charging. They apparently messed something up with USB-C because power delivery adapters just don't work (C to C cables). Apparently only A to C chargers will charge these. Kinda annoying since most of my chargers are C to C now. Second thing is ergonomics - they're either too big or too small for my whole hand - if I press the curved part in my palm my fingers end up not getting warm, and if I rotate the device so my fingers are over the curved area it bites into my palm. I can deal but it's a little frustrating.However, they did their job and stayed warm in subfreezing temps for two and a half hours, and probably would have kept going - after the game I was at about 50% charge. I kept them in a hoodie pocket so they warmed up extra quick and used them on the ride home to keep my hands warm until the car heater kicked in.
