Lentra Hot Hand Warmers 11 Hours Long Lasting - 40 Count - Natural Odorless Safe Single Use Air Activated Heat Packs for Hands, Toes and Body - Up to 11 Hours of Heat - TSA Approved

I’m hoping this review will help others debating on buying these, as opposed too paying much more for the name brand competitor.To start, these work just as good, if not better than Hot Hands. Not only do they last what seems like forever, they literally get so hot, that depending on where I have them, I have to put another layer in between the packet and my skin.After opening each packet, I’ve found they do need a good shaking. Personally, I put one in each hand and shake them both for about 10 seconds, I then set them to the side for a couple minutes, while the air “activates” the ingredients in the packet.Personally, I found that if you immediately put them to use after opening, it takes them much longer to heat up. I guess it’s just preference, but thought I’d pass that info along.Lastly, PLEASE be cautious, especially when giving to kids as these do, eventually get REALLY HOT! Do NOT put the packets directly on your skin! Make sure you have some kind of clothing or layering between you and the packet, to protect your skin.Well, hope that helps anyone who was hesitant on these. There worth every penny!

Cheaper than name brand, but works just as good. Never have to worry about keeping all of my hands warm.

They should really just describe this Hot Hand Warmers 11 Hours Long Lasting (40 Count) as having 20 pairs, so there's no confusion. The price is affordable, especially compared to other brands. And value is even better, especially if you use the various coupons & discounts that pop up. If the info & instructions were on each half (so packs could be separated in two), then it would make more sense to call this a 40 count or 40 packs. But they can't be separated without losing half the product info on each packaging, so they should be considered 1 pack (that includes a pair in each pack). The product photo of the box does reflect it contains "20 pairs per Box", but not everyone may notice that tiny print on the photo. As for the hand warmers themselves, they do get warm, though maybe not that hot. I put a couple under my feet to warm them while I'm sitting in my favorite armchair watching C-dramas & K-dramas on TV. Or I slip one down the back of my PJ top to warm my back as I huddle under my blankets as I try to fall asleep.

These are perfect warmers for the homeless. We do an annual mission downtown and a few these go in each bag. Good size and they stay warm for hours and a functional for feet too. Adhesive?

I bought these as a gift and the person loves them. They get cold easily and always carry these in their purse.
