LotFancy Reusable Hand Warmer, 6 Click Activated Instant Heat Packs and 1 Wrap, Gel Heating Pad, Snap Hot Therapy Compress for Pain Relief, Outdoor & Small Portable Size

I love these little round reusable hand warmers. I take them everywhere I think I will be cold. Put one in each of my pockets for yoga class.

I have it for 2 years and it still works well. You can take it anywhere and reuse it as many times as you want to.

Easy to use packets that are convenient and reusable per the instructions, last about an hour for warm but not hot heat, wish they lasted longer

The package contains six pads. Theoretically, a click on the little disc inside the pad activates it and starts the heating process; however, my experience was different. I could only "click" three of the pads, and only one of them produced any heat. 1 out of 6. That's not good enough for me.That was how my first review started; however, I've since learned more about this product. Now, my only complaint is in how it's marketed. Clicking on the little tabs (called metal coins in their advertising) is a very poor way to activate the discs (1 out of 6). What you must do is to BREAK them however you can. Once you do that, you'll hear an audible sound, and the activation begins.As to the usefulness of the activated pads, I now have nothing but praise. They furnish the needed heat quickly and easily. Now, the heat doesn't last that long, but it is quite sufficient for the purpose for which I bought them: the treatment of earaches; however, I wouldn't expect them to be of much value for serious muscle aches, such as leg cramps. For that, something stronger and longer-lasting is probably required.

Glad to use these year round, easy boil and reuse! I have noticed these aren't as hot as others I have had in past however makes them great for younger kids. Love it comes with a pouch for ease for little children

Total Fail. I was unable to activate any of these heat packs.

These are nice and work great not just for hands, but anywhere you have a small spot that's sore. I used them for a stye on my eye

I was really hoping these reusable hand warmers would be a convenient and eco-friendly way to keep my hands warm, but unfortunately, they didn’t quite meet my expectations. Out of the six packs, I accidentally broke two while trying to reset them for reuse, which was disappointing. The discs are pretty small, and they don't seem to heat for as long as I’d like, making them less effective on really cold days.Overall, while they do work for a quick burst of heat, I’d recommend saving your money for a more robust version that lasts longer and is a bit easier to reuse without the risk of breaking. Save your money.
