LotFancy Reusable Hand Warmer, 10 Click Activated Instant Heat Packs and 2 Wraps, Snap Hot Therapy Compress, Gel Heating Pad for Pain Relief, Outdoor & Portable Size

Great hand warmers. We use them anytime we go to an amusement park or a convention. Easy to maintain and very affordable. I will be buy more in the winter.

These work great and heat up pretty quickly . My daughter uses them when her sinuses act up

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.

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.

If you are in need of portable, instant pain relief, then this is the product for you. I purchased these in anticipation of international travel, as I did not have room in my suitcase for a traditional heat pack. The set comes with 10 click-activated warmers--that are super easy to use. It's amazing how quickly upon activating (ie-simply press on the small piece of metal inside the gel pack), the chemical reaction occurs. Once activated, the pack begins heating, and it's ready to use. I like that it is small, and can mold to areas in need of relief. Once finished, it is easy to "re-set" by placing in boiling water (directions included). If you are wondering how this worked when traveling, in all of my hotels, there were hot water dispensers/teapots, so was easy to accomplish-by placing inside a cup with the boiling water). You can also place the gel pack in the refrigerator and use as a cool/ice pack. This is a great set for those in need of reusable heat/cool packs.

Half of the warmers do not work even when snapping the metal disc inside. Waste of money and completely useless.

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
