I purchased two handwarmers, because I have been suffering from Raynaud’s syndrome for years and years and every winter, it seems like it’s worse and more painful for me. I thought that having these handwarmers would be great and they were advertised and endorsed by the Raynauds foundation. Also, I noticed that a lot of other reviews people that suffered also had highly recommended these particular handwarmers so I thought I would give them a try. I originally had ordered two others of the same brand that were different color and when I received those one of the units was defective where the lanyard hooked onto the unit so I had to send that one back and I got a replacement in that one also two was defective as it would not hold the lanyard in place. So I sent it back and got a refund and ordered the two in Camo and when I receive those they both were perfect. So I kept the other one that was good from the original first order now I have three handwarmers. Want to keep in my car and two to keep in my purse at all times the heat up really quickly. They are very comfortable. they’re easy to hold. I have rather small hands so that is a big plus there as well. I like the feature that they have an additional plug-in where you can actually charge up a partial charge for your cell phone or other device if needed, I highly recommend these hand warmers for anyone who suffers from a Raynaud’s or who has cold hands in general a lot. They are easily stored in a pocket or purse, or in your bag. Great value for the money.

Can’t give a review. Because I haven’t received itBut, I used one in class 2 weeks ago. And loved itThat’s why I ordered one

The warmer lasts 9 hours on the lowest setting. I tested it in the house in normal room temperature settings. The warmer gets very hot, especially on higher settings. I haven’t tested it in the rain for being waterproof, yet. I will be taking it into the woods for further testing in the elements

Great product. Works well

Good hand warmer. Battery lasts through a 4 hour hunt on medium. Keeps your hands warm.

Quality made and heats up great. Bought it for golf, but now using it while blowing snow. Don't really know how long the battery lasts, but have had it out 3 times so far on one charge. Tough little unit.

I have two different rechargeable handwarmers. I got this one because I wanted one that would last a long time, especially while the other one is charging. It lasts a long, long time, like 8 hours. I only use the lowest heat setting because the other settings are too hot for me to hold. However, I am mostly using this indoors. I will put it on the medium setting and throw it in my bed to help pre-warm the sheets. And I'll use the hottest setting to heat my socks before putting them on. Mmmm, so nice.But I probably wouldn't buy this model again. It's just not that nice to hold, especially compared with my karacel version. It's kind of a lumpy shape and the material is rubbery/plasticky. It doesn't get warm all over -- the end with the outlets barely gets warm. The rubber bumper on the outer edge is a flat gasket, and you can push it off or wrinkle it around. The karacel is made of a very smooth powder coating and is a delight to hold, with no funky bumps or gasket.The handwarmer works as advertised and it was packaged so nicely. This would make an excellent gift because of the nice packaging and boxing. If I didn't have the karacel I wouldn't know what I was missing, and I still think this one is a good product. But I'd rather have 2 shorter lived karacels (or 3!) because they are smooth, fit in a pocket comfortably, and nice to hold on to and hold to your face or neck. No, I don't work for karacel! The karacels probably only last 3-4 hours.Also, you should know: the handwarmers cycle in intensity. This is totally normal & good. It will get much hotter for about 10 seconds, and then fade to a longer period of comfortably warm. I believe this is designed that way so you keep your sensitivity.

This hand warmer is a single unit and heats up both sides. I find that it does heat up slower than most 2 pack hand warmers I have tried. It does eventually get warm, but I find that I need to use the highest level to get good warmth. It is not the hottest hand warmer out there. It does work as it should and you can also use it as a power bank to charge up your phone if you need as well. I still prefer having a unit for each hand in each pocket and in this case, it would be very pricy to buy 2 for this purpose.

Warm hands in the recent cold weather. I hadn't realised it works as a power bank too. Brilliant for charging the phone !

Warm on both sides. Good to have the option as a backup battery. The strap is good for carrying while warming the hand. Yes, a bit pricy.

I recently purchased the waterproof, rechargeable handwarmer for my husband and I am extremely impressed with its performance. The heavy-duty design and large 10000mAh battery provide up to 15 hours of heat, making it a great choice for outdoor activities such as hunting, fishing, or camping.This is the first waterproof handwarmer I’ve seen, which is really a great feature because I know this will most likely be dropped in the snow and slush. It is the perfect accessory for all his outdoor activities, as it can withstand wet and harsh weather conditions without losing its performance. The desert camouflage color is a nice touch, and it blends in well with my husbands hunting jacket. It quickly charges to its max capacity in approx. 3 hours, and can be used as a backup battery pack to charge your phone or other devises. That way there’s no excuses for not having his phone charged.This is an excellent handwarmer/battery pack, great for everyone especially the hunters out there.

A good little product. Easy to charge but controls a little fiddly to operate until you get used to them. They do the job and stay charged for a long time. Ideally you need two, one in each pocket.
