Gave this to my builder so he would work on cold days He siad it heats up in seconds .

I have not had any issues with this product. I purchased it on an Amazon influencer discount. I actually bought two of them one for myself and one for my boyfriend. I live in Wisconsin in Winters can get very cold for us. My boyfriend gets cold very easily and with his job is in and out of buildings a lot, I gave him this to take to work and he actually didn't really want to he thought it was silly. Just so happened it was an extremely cold day he was with two other men at work who were freezing. He handed them this thing and they started to fight over it because it worked so well. It gets extremely hot and will keep your hands very warm. Thankfully this year in Wisconsin it didn't get extremely cold for very long so I can't tell you how the battery life is but so far so good.

Just bought my second set of these hand warmers. My first set is still going strong, but they had a great deal I couldn’t pass up. Usually the lowest setting is perfect with my warmers. Sometimes will do medium. Highly recommend

I bought this for my mom as a Christmas present. She's a dedicated grandma and goes to ALL the games regardless of the weather to cheer on her grandsons. These have come in handy more than once! They get nice and hot and last a few hours. I've used them a couple times if I forgot my gloves. only complain is they are a little bulky if you have smaller hands, and they don't heat super evenly. Trust me, they do a great job of keeping you toasty still! It can just get hot spots that make it really hot in one area and not as warm as it should in another. I would definitely buy again though!

These have been great to take to the ball games. They last a good while. I keep one in my car through the winter. They have come in handy.

I bought this handwarmer for my mechanic husband and he loves it. It lasts a while and gets very warm.

These heat up really quickly to the point of being hot. My wife likes them so much she brings some with her when we travel.

The media could not be loaded. Everything that was mentioned is true. It heats up on one side and can heat up on both sides. To test its battery, I have slept with it on the first setting with one side heating up and I kept it on for 10 hours, that’s how long I slept on that cold day, and there was still battery left to continue using it. That being said I used it in the first, low setting and only one side. I will say that sometimes even in the lowest setting and can become too hot but then it’ll change. This isn’t a big issue for me , I don’t mind it but some people might complain that it burned their hand. I had no issues charging it, it comes with everything you need to charge it except the charge let adapter. other than that, it works great. It warms my hand. And it’s perfect for the winter in NY.
