Review: Interesting product, read review - Mesmerized after you snap the metal in the pouch to activate the heat. Gives off good heat, not burning hot but tolerable. Made well! Read instructions and boil for 10 mins. after use to get back to gel. Pain relief is an 8 out of 10, very easy to use, design is perfect for minimal notice and small areas, very effective and extremely flexible. Great product!!
Review: Good product at a great price! - Very good hand warmers and great for the price. I really like these because they are very portable and you can take them anywhere. They have no smell and create a good amount of heat. One thing I wish it had was greater life span and had heat for longer. Another thing to note is that i think they can get a little bit less effective the more they are reused. It is also kind of a burden to have to boil them every time you want to reuse them. But overall i think this is a great product and diffidently one that you would want in the winter.

## Questions & Answers

**Q: How long does the heat last?**
A: Thank you for your question. The duration of heat depends on the condition in which the heat pack is activated. Overall, it should last between 30 and 45 minutes. For example, if you are going to be using it outside in extreme cold, we recommend carrying it inside a coat or pocket. The colder the starting temperature of the heat pack, the more energy it will required to heat up and ultimately affect the length of time the product stays warms. We hope this answers your question!

**Q: Could I use it to keep my food warm in my lunch box?**
A: Safe holding temperature for hot food is min 140F. These only get to 130F and reviews say they last an hour or less. In short, I wouldn't recommend them for keeping food warm. Look into vacuum bottles, such as Thermos for food safe options.

**Q: How many times can these be reused?**
A: Our heat packs are built for durability and longevity so there is no limit on the number of times you can reuse our heat packs. If you encounter any issues please reach out to us directly at info@hottogoheatpacks.com and we promise to do our best to resolve your issues. Thank you for your question.

**Q: I'm looking for heat packs to use in my wetsuit while scuba diving.  Would these work?**
A: We use heat packs like this one all the time while diving. In fact, I was looking them up to buy more for that purpose.

Our typical use is to warm students hands between dives, but we have used them in wetsuits. As Amy pointed out, it's best not to put them directly against the skin, but they work well over a dive skin and under the wetsuit. They also work in a dry suit, but again, not directly over the skin. But between dives, when your hands are wet and getting cold int he breeze, they are amazing!

### ⭐⭐⭐⭐ Very nice, but don't last as long as advertised
*by A***R on December 26, 2019*

I bought these as stocking stuffers for my wife and kids and I'll say upfront that I'm pretty happy with them. Positives...All 4 packs seem to work as expected and none of them had already "activated" in shipping. They heat up quickly and at their hottest, feel warmer than those cheap throw away ones...I say feel because I haven't actually tested the temperature. Boiling to "recharge" them was no big deal and I like that they can be used repeatedly as I try to avoid creating needless garbage when I can and the throw away ones are needless garbage. They are made of a thick plastic/vinyl material and while I'm sure I could rip one open...they don't feel cheap. On the downside...Like some other reviews have mentioned, the initial activation took a few tries to get it going and I was worried that they were duds. But we just kept trying and they eventually started. On subsequent uses they seem to trigger right away. So I'm sure it just has something to do with breaking in the activator. If you have trouble getting them to start, just keep clicking the little metal disc and it'll eventually go (probably). Also, I wouldn't say they really last as long as advertised. 30 minutes on the larger size is about the max and probably 20 minutes on the smaller size. When started, they quickly hit their peak heat output and then slowly start to taper off. I'm wondering if they might last longer if they were wrapped in something? Not sure on that but I'll probably see if I can figure something out. But yeah, overall they are nice and I'm happy with the purchase.
