Great for Hunting, Ice Fishing, Snowmobiling
I suffer from always being cold, as well as Raynaud Syndrome. I used this for sitting in my hunting blind this fall and it worked fantastically. I have a hand-warming pouch I keep it in, and it keeps my hands perfectly warmed. On the highest setting, it's barely able to be touched with bare hands. I kept it on the low and medium settings. It lasted about 3 - 4 hours, which was fine because that's about the length of time I was using it anyways. It is a bit heavy, but that's not worth knocking stars off for. I don't see the need whatsoever for the colored lights around it; that's completely pointless to me. For the price, I'd much rather have this than go through $20 or more worth of disposable hand warmers per hunting season.

Great warmth with a good battery life
This item can get warm. From 'Eh, I can feel it' and 'That's a nice heat.' up to 'Ow! Hot! OW! OW!' at its highest. Working Retail in Frozen/Dairy has been changed completely using this, so much so I tend to leave it on when putting it back in my jacket pocket if I'm still inside the cooler/freezer, and so my battery usage is rather high. Depending on how much I use it (turning it off once I'm out of the cooler for instance), I can get one or two work days worth of good heat from it before the battery dies and needs a full recharge.The RGB color stripe around it is nice, but harder to see in the bright lights of a grocery store, and the colors don't quite reach the entire length of the visible strip. It's nice to have though.

Love the color to keep it away from hubby
I have bought three hand warmers now. Hubby confiscated the first two. I thought if I got a pink one I could keep this one for myself.They last a long time on one charge and get really warm.I can't use those ones you "break" to heat up. They never warm up for me and die as soon as hubby hands me one he has warmed up.These always work, as long as they are charged, and there is no worry of pollution from throwing away a hand warmer.Works great with my neuropathy and arthritis to keep my fingers from getting painful in the cold.

It works and it's Hot!
I love this hand warmer. It's easy to turn on. It warms up quickly and the high setting can actually get too hot inside but is perfect for super cold days. Keeps me warm while my car is defrosting and I'm outside cleaning off the snow and ice. The colors are pretty too when I have time to appreciate them. There are 3 different ways to plug it in for charging. I bought 2 so I can swap them out every day. Thank you for a great product!

I would recommend…
Keeping an eye and or keep it plugged in when not in use, purchased 4/2021, worked great those winter days, but I just got mine out of desk storage and it seems to be having issues charging… I will update this review later after its had a chance to take a charge, I could be mistaking, but I thought the display flashed the percentages, but shows a solid 25%. Also faintly glows red upon inserting a charge cable? [Update] It took nearly 18hrs of the display showing a steady 25%, but lo & behold some 8hrs later I see it blinking, ok… the next morning(now closer to 48hrs), it’s still flashing only 25%, then I remember that I used to have to switch from a USB-B to a USB-C cable, don’t know why…? But now after nearly 4.5days it’s fully charged, so I guess good luck with yours and hoping this post might save some of y’all’s devices from an early trip to the e-graveyard. Stay warm and healthy! 😎

Excellent product!!
A bit expensive, until a few days later it was on lighting deal for cheaper. So I got one for my mom too.Now read this before you pass up on this one.At first I was very disappointed that it wasn’t that warm or hot to my desire. I was ready to return it, but I love the color so much! Then a few nights later I turned it on and left it in my pocket and it was keeping me warm! So later on that night when I took it out it was super hot! Like no kidding, hot to the point where you cannot put it directly on your skin. It prob won’t cook your skin, but enough to make you remove it right away.

If you have Raynauds, this helps!
I like that it has 4 different settings. When my fingers start getting numb, I can easily hold this in my hands & it warms them right up. It’s easy for me to take out on the playground with my preschool class too. They love the lights, a little extra fun! It charges pretty quickly & holds power a long time.

Want to, but Can't Love These
My son and I both have Raynaud's disease. I have bought seven of them in the past year. A pair for my son, two pairs for me. Then, I lost one of mine, replaced it and later found the one I lost. I've seen three brand names for what look except for logos like identical devices. I've bought two of them and they are identical as far as I can tell. They do keep my hands warm, so I want to love them, but I can't.First, don't lose the cloth bags. On their higher settings, they can be too hot to handle comfortably.Second, they don't work for as many hours without recharging as the sales blurb suggests they will. Not nearly as many.Third, and most important, the batteries aren't consistent from one unit to the next. Of the two I bought in February, one of them runs out of power and needs recharging a lot sooner than the other. Of the other three I bought in October-November, one of them also won't hold a charge nearly as long as the others. So, two out of five aren't nearly as long-lasting as the other three. In addition to being a hand-warming problem, the inconsistent battery life makes them problematic to use as external batteries to charge other devices.Lastly, I don't know about you, but I keep hand warmers in my pockets. So, as far as I'm concerned, the light displays are absolutely useless.
