Hand Warmers - Premium (Size: 3.5 inch x 4 inch, Duration: 12+ Hours, Max Temp: 163 F) Air-Activated, Convenient, Safe, Natural, Odorless, & Long Lasting Hand Warmers

Read carefully: you get five total hand warmers, not five pairs of hand warmers. That being said they are larger than the average size. They stayed warm in a pocket for about 12 hours.

Sooooo... it took a while to heat up... shaking and massaging it gently is not working for us. We literally have to pinch and grind to get heat started... but it works.

I was a little hesitant because my first pouch I opened didn’t warm up. Then it started to slowly and throughout the day it was nice and toasty. This product does warm up like the packaging states and does last a full shift and overtime. I recommended to my coworkers. For the price and the quantity, it’s a good deal. We work in 30 degrees and sometimes down to -5 so we always have these ready.

We ordered two 5 packs to try them out. The first pack worked great. The warmers heated up fast, and lasted as advertised. The second pack did not work as well. The first warmer worked like the first pack, but the next 3 warmers were duds. They did not warm up at all. What a waste!!!! We ordered a different brand and we'll see how the work. Won't buy these again.

These hand warmers are wonderful! I have tried many brands, but none of them get warm enough for me. These get nice and toasty, and they also last a long time. Will continue to buy for sure. (I have no relationship to the manufacturer. This review is just based on my experience with these warmers). I have been looking for these for a long time. TIP: I often only use them for four or five hours. If you put them in a sandwich ziplock and squeeze all the air out they will work for at least 2 more times, but for me, since I use them for about four hours, they last three times.

I switched to these from HotHands for three last two ski trips. My hands are always cold within 30-60 mins of being outside. OMG, these last for over 12 hours vs HotHands after they switched their active ingredients to source from China. I only wish ThermaHands made toe or foot warmers.

Label says "max temp of 163 degrees" and really lucky to get to 80. These really aren't great for actual warmth. I was using these for house plants to force a bloom and replaced these with an electric blanket. The price is great, but delivers that price too. Meh.

Stick with what you know, these didn't last or heat as well as the familiar brand

Easy to use

OK

They last slightly over 12 hours & a good size for me which covers my entire palm (I don't have big hands so it's better to refer the actual measurement here). And one plus for me is that they are made in Korea where I used to get all my previous hand warmers for years - that I know good qualities are guaranteed.

They kept me very warm, however I only neede them for an hour walk & it was kind of o waste...because the heat lasts for several hours & then you can’t use them again. So I had to throw it out after just wearing for an hour!

Way too big and bulky. Not good for skiing, hiking or active sports. Probably okay for standing around with these things in the pocket.
