Product Description

How to Use HotSnapZ Reusable Heat Packs
Gently click the internal activation disc
- The activation disc is the key to starting the reaction.
- The clicker has a slight curvature in one direction and the best way to 'Snap' the disk is to grab the edges and gently flex the middle of the disc to reverse the bend till it "clicks"
- Once snapped, you will begin to see the crystals form. This is when the fun begins!
Crystals form releasing the stored heat
- Crystals form releasing stored heat.
- Self-regulating reaction and safe soothing heat.
- Heat will generate 20-40 minutes depending on the product size and use.
- For maximum performance keep product at room temperature before clicking.
Recharge in boiling water
- Once the heat is expended, your HotSnapZ can now be recharged!
- The heat of the boiling water dissolves the crystals back to the original liquid state, storing the heat energy for later use.
- Once all the crystals are dissolved, the product is now recharged and removed to cool. Once cooled, the clicker is then clicked to release the stored heat energy.

Details on what is in this HotSnapZ pack:
Our two most popular reusable hand warmer sizes
4 Round HotSnapZ Hand Warmer + 4 Pocket sized Hand Warmers
Receive a total of 8 items consisting of the following:
4-Round Reusable Hand Warmers (2 pairs, 4" diam., 4 oz. each) - Palm Size

Instant easy heat at the click of a button.
How hot do HotSnapZ reusable heat packs get?
The chemistry inside HotSnapZ is a safe and self-regulating reaction. The maximum internal temperature reaches 128-130F and typically 115-120F at the surface during normal use. The temperatures that HotSnapZ operate at are considered to be non-burning when used as directed.
What is inside a HotSnapZ pack and how does it work?
HotSnapZ reusable hand warmers and heating pads contain water, a small metal disc and sodium acetate, a safe food grade salt ingredient. Click the click to release the heat. Once the heat is done, simply drop your HotSnapZ hand warmer or heat pad in gently boiling water for 5-10 minutes to recharge.
How many uses can I expect to get?
In theory, the number of times that a HotSnapZ can reused is infinite. However, the consequences of real life usually take their toll on HotSnapZ at some point via wear-n-tear, being torn, stepped on, forgotten in the boiling pan or having one of your friends walk off with them. So, we expect and tell the average user to expect 200-300+ uses if properly used and stored.
How long does the heat last?
Heat duration depends on the product's size, how the product is used, & how well the product is insulated during use. Our larger Rectangles, Neck and Shoulder products are rated at 2+ hours of heat. Our green rectangular Pocket Warmers at 50-60 minutes each and 30-40 minutes for our Round Hand and Heart Hand Warmers. Extended heat times are achieved by having some extra ones in reserve! Remember....HotSnapZ are REUSABLE!

- Reviewed in the United States on December 5, 2013I'm rating these 5 stars because I'm definitely a fan. But it's not all good news to report, so I'll give you the good and the bad. First the good. Because these are re-usable, these things do save you a lot of money. Also, they get much hotter than most hand warmers, and they're really fun to use, and to show off to people. Seriously. FUN! However, they don't last very long before cooling off. I generally only get 10 minutes of strong heat, and then another 15 to 20 minutes of it slowing going from warm to cold. There are things you can do to make the heat last a little longer, like kneading them repeatedly. Also, if you keep them in your pocket, they last longer than if they're out in the cold air (logical, right). And someone else suggests you heat them up before activating them, which slows the 'freezing' (heating) process (I haven't tried this yet, but it sounds like it makes sense). Another thing is, it can be a bit of a pain having to take the time to boil these every day after using them, and personally, I've been lazy about it, and often let them sit for several days before boiling them. This is something you need to avoid doing. You need to boil them down right away. Don't let them sit in their hardened state. If they're allowed to sit, for some reason, when you do try to boil them down later you'll have a much harder time, and sometimes not be able to at all. I don't know why this is, but it just is. I've ruined a lot of them that way. So, learn from my mistake. Also, regarding their pretty color and appearance - don't expect it to last. The color fades quick, and they start to look really ugly. But it's not about looks, right?
- Reviewed in the United States on February 20, 20152019.02.22 update:
hotsnapz.com honors their lifetime warrantee. We have had 16 in constant use since Feb 2015. Two have gotten lost (not covered by warrantee), and two have failed. I called hotsnapz.com; the warrantee is very simple: you pay for shipping, they ship you a bunch of replacements. Even though I bought them through Amazon, they had my purchase on record so I didn't need any paperwork to prove my purchase. I spent $8.00 for shipping, and they sent me 10 replacements. I do not have to return ship the two dead ones. Fantastic!
2015.02.20 Original Review:
Awesome! And Easy to Use (with practice). Green ones are best.
These are great little hand / back of the neck / bottom of the back warmers that last about 15 minutes. Please note that they are too big to fit inside standard fitting gloves. We love them in the evening while watching TV and to warm up freezing fingers after working outdoors.
To use: flip the metal piece back and forth so it snaps. Maybe that's obvious, but it took me a few tries to figure that out. Then mush the stuff all around to make it heat faster (and probably last less time).
To recharge: I use a pasta pot (look for "Stainless Pasta Cooker 8Qt Stock Pot Strainer Lid Set" here on Amazon to get the idea); that way there is no chance of one hitting the bottom of the pot and burning. I put the handwarmers into the top part, bring the covered pot to a full boil, turn down the heat to simmer (still covered), and set the timer for 15 minutes. After 15 minutes, I use a plastic spatula to fish them out and put them on a cooling rack. I then pour the boiling water down the bathroom sink to help keep the pipes clear.
We prefer the green ones, and when we order more, will exclusively get those. The red ones are nice but too small.
- Reviewed in the United States on January 21, 2025The keep warm for a decent amount of time. One of them had a leak. I tried to reach out to the seller with the app but it didn’t work. I didn’t return because I needed them and didn’t want to wait for another delivery. Overall I would say they are worth buying.
- Reviewed in the United States on February 17, 2025Do not put in the microwave to boil water to reset!
We love these in our house but recently 1 of each of the shapes was put into a 4 cup measuring cup with water to reset and as the water was boiling the air in the pouches heated also and floated them to the top and the plastic continued to expand until we had leaks.
My little dude loves "pushing the button" and "making the crystals get warm". Not only keeps you warm but a cool science experiment.

5.0 out of 5 stars Great product, great value!
So convenient and love that they are reusable. Hot heat lasts about 30 minutes and stays warm for another 30 minutes. Long enough to warm those fingers! Also we use them as a "hot rock" replacement prior to massage! Great product and will definitely buy more for gifts!

1.0 out of 5 stars Only heats for 10 minutes
I wish i had read the negative reviews before buying. These only heat for about 10 minutes even when starting indoors. Large or small pack makes no difference. I’m surprised they advertise this as lasting 30 min to 2 hours.
Usb Rechargeable hand warmers like Ocoopa are much better

2.0 out of 5 stars Not up to the job.
Massive disappointment. Got these for when I watch my children play football in the cold. They get warm quickly but hardly lasted even 10 minutes and definitely didn’t keep me warm or warm me up even a little bit. Total let down and I’m really annoyed I’ve wasted my money too. I wanted to get something reusable but I’m likely to go back to disposable after this awful product. Do not buy.
