I was looking for a hand warmer to use during competitions involving my hands, so I need something that will provide fast warm up. The interior gets warm but doesn't give off enough intensity for my needs. I will keep it but will supplement with some of the common hot packs. If it were a little more robust I would rate it 5 stars. It would be great for something like spectator sports where the hands could be kept inside it for longer periods. Cuffs are good, heat settings are easy to use, uses a typical USB battery source. Strap is very basic. Overall very good basic hand warmer muff.

My hands hurt all the time, but i don't have time to put on and take off heated gloves for pain relief. This handwarmer saved me! Thank you!

Very warm and cozy. The battery isn't too big.

My boyfriend loves this, it works great!!!

Hey, lookit me, I'm a quarterback! Nah, I gave this to my aunt as a Christmas gift to help with her chronically cold hands. She says it has helped a lot.

I knit and crochet and this muff helps keep my fingers warm in between rows. Without it, it would be far too difficult for my old hands.

I work on aircraft repairs and the hangers can be downright frigid in the winter, and you can't wear gloves because you can't feel what you're doing. This muff helps, I just stick my hands in for a few minutes and I'm ready to get back at it.

This Muff comes in handy (get it?) when Im out in my treestand and gloves are too bulky for my trigger finger. Keeps fingers warm and flexible for when the time is right.

I got this to wear to keep my hands warm on my morning walks. it has a huge heat panel right where my hands lie inside. The strap adjusts easily and I can take it off with one hand.

I like to knit at my kid's games but find it difficult when it's cold outside, so I bought this item to warm up my hands and fingers without having to put on and take off gloves. The heat panel is HUGE and heats up very quickly. Sometimes I just leave my hands inside and forget to knit!

The price is nice, it's a lot cheaper than decent heated gloves, but does great at keeping your hands warm when they are in the muff.

Think of all the times you were outside, and your hands were freezing, so you put them in your pockets. This is just like that, except those pockets are heated!

Can't wait to see Tom Brady wear one of these to fight his old man arthritis during Superbowl 100

I feel like either an idiot or a quarterback wearing this, but hey, my hands are warm and that's all I really care about. I'm a roofer so I like to have my fingers free and gloves just are too bulky for me. Whatever works, eh? And these work!

Great for bowhunting! Needs to come in camo now. I got a couple extra batteries so I can keep the heat cranked up all day out in the woods. Helped me bag a 10 pointer.

Looked too much like a fanny pack for me so I gave it to my mom. Her church is drafty so I told her this should help her.

I need to keep my fingers uncovered for work purposes, but they do get cold. this was the perfect solution. I can pop my hands inside for a quick heatup and then get back to work.

I work outside and need to have as much dexterity in my hands as possible, and gloves are just too limiting. I love that I can just keep my hands in the warm muff and don't loose any control

I just wanted to write and tell you how much I appreciate how quickly you sent my hand muff. I have a hard time putting on gloves, but this is so easy for me to just put my hands in and feel the nice heat. it lasts a long time and the battery is easy to take out and charge. Thank you very much.

For some reason, my two kids like to take turns using the muff. It definitely keeps their hands warm for a long time while they stay indoors. Going to pick up a second one for sure!

Bought this muff on a whim while buying extra socks. I was surprised at how well it kept my hands warm when I tried it.

Now I look like a quarterback, and also have warm hands!

The heating this product allows me to brave the coldest day in D.C.

Bought this for my kid who is going on a camping trip. Order arrived on time and the muff keeps him warm. Couldn't be happier about my purchase.

Cold hands will never be a problem for me as long as I have these!

I purchased this hand warmer for my elderly mother who has chronically cold hands and suffers from arthritis and cramps on really cold days. She uses them regularly and can now spend time outside during the winter with her chickens. The product seems well made and has perrformed flawlessly.

I wear this to outdoor sporting events and this hand muffs works wonders. I love it

I really dont like wearing gloves so when I came across this muff I thought Id give it a try. Turns out it was a really great decision because it keeps everything warm from my wrists to my fingertips and I dont feel constricted.

My hands are really warm now during outside activities

My hands get cold so easily so this is really a must-have for me. I really don't like wearing gloves as most of them are too bulky and it's ridiculous to wear gloves at home. I just hoped the battery could've lasted longer but aside form that, I have no complain.
