Warms your hands just as it says! I plan to order them as Christmas gifts for my female relatives.

These keep your hands warm, but aren't too thick so I can still do outside chores. Not waterproof but otherwise great

They're warm.  There's not a whole lot you can write about gloves.  One thing that's really nice (and not really indicated in the picture) is that the part of the glove at the wrist will actually roll down pretty far on your arm and help keep the cold out of your sleeve.

I like these gloves. They are well constructed, warm and comfortable.
I bought these as winter driving gloves. They have excellent grip on the fingers and palm.
Only minor disappointment-- Not as form fitting in the fingers as I would have liked, but not big deal.

Details of the fit for me:
I measured an 8.5 around the palm and purchased a size 9 due to other reviews.
I have a medium size hand thickness, and I do not have long fingers. There is slightly more extra material at the tips than it looks like in the picture. So this limits the dexterity a bit.
The glove is snug around the knuckles and upper wrist-- especially when making a fist. They are a little stiff. I have only worn them twice, but I think they will likely loosen up a bit.
Example of dexterity: You could probably adjust your windshield wipers, lights and maybe even your radio, but without removing them you might have trouble getting to your wallet and removing a bank card.

So far, they've helped to keep my hands pretty warm. I have small hands and thin fingers, so my digits are always difficult to keep warm in freezing temps and I really have to protect them from frostbite. Having the mitten feature allows for the fingers to share body heat with each other and if needed, I can toss a little heat pack in there. The ad pictures did not reveal how the mitten pouches keep from flapping around, but there is a little velcro patch to keep them secure when you don't need it. I've shoveled snow with them now and they do a decent job at keeping my hands warm. The only thing I dislike is the weird gasoline smell these have when you first wear them, kind of like military gear. I'm sure if I remember to bring them to the laundromat with me next time, that will remedy that issue - I think I'll just avoid drying them since I don't want to risk them shrinking?

Update 1/3/16: I've now been working with these gloves below 32 degrees F and these are definitely not a good idea when it's that cold. My fingertips cannot stay warm enough and lost feeling in them on one cold day while shoveling snow. I still like to wear these when it's at least above freezing because of the versatility with my fingers when needed. I have thrown these in the wash and the gas smell is still on them, so haven't been able to remedy that very well.

I just got these today and went for an hour walk in 6 degree weather here in SD.  My hands stayed nice and warm.  I know I'm going to love these glove all through the winter months.  They are well worth the money.  They also look very nice.

These are my second pair. I use them with Grabber brand heat packs in the magentic pockets. It keeps my hands warm while I get the bus going while holding the freezing steering wheel, until the heater kicks in, then I can flip the glove ends to stay just comfy.

Keeps my hands warm in above freezing weather. We'll have to see how they hold up in really cold weather.

These gloves keep my fingers warm. No small feat, as they have been going numb and turning white for some time now, any time the temps drop below 50F. I have yet to turn them past 2 dots on a scale up to 4 and that in temps down to the upper 20sF. I took one star off because the controls are pretty clunky and take a while to figure out. You start out at 4 by pressing the button. Then you have to release it and figure out how long to release and then hold the button down to get it to drop down to 3, repeat down to 2, repeat down to 1. Or, it might just drop you all the way to completely off. Clumsy at best and quite annoying. The controls were designed to be cheap, not user friendly. Still, once you get them set to the right temp, they really do the job.

I work outside and one of the best gloves I've used for winter.  Truly keeps your hands warm, and there cozy.

I wish I had bought these long ago. My old hands get cold easily and gloves never seem to work. But with these in below freezing temps my hands actually stay warm! I was a bit worried that they wouldn't be so good because they were relatively inexpensive when compared to a lot of good winter mittens.  Very happy they work so well.

I ordered these gloves for every day winter use.  They have successfully kept me warm -- even at 0 degrees Fahrenheit.  They also worked well as substitutes to snowboarding gloves for a day, though I wouldn't recommend it for multiple days in a row unless you use a hair dryer or something to dry them. The convertible glove feature is very convenient.  There is a small piece of velcro located in two locations to keep the flap attached to the back when you want to use your phone or get your keys out, but sometimes it can be a little annoying when you have it in "mitten" function and the velcro sticks to certain material.  Overall, I am very pleased with these gloves.

Wonderful.  Keeps hands warm. Wish for more size choices for other family members.

Well, if the past two winters here in the North are any indication as to what may lie ahead, these should hold up to mother nature quite nicely. Very nice thick pair of Thinsulate Thermal gloves. The Color of the gloves will easily go with anything in the brown, blue or grey family of attire and the comfort is spot on. The gloves appear to be very well stitched and fit my large hands nicely. They slide on and off with little issue and the suede front allowed me to grab my mug of coffee this morning with no problems. Real nice overall fit and just feel nice on the hand.

(I did receive these on a discount for an honest review)

These gloves are great! I've worn them everyday this winter when going outside pretty much. When I go to my car, work or grocery store, I have these on. They're very warm and very comfortable. I can wear them down to probably 10-20f by themselves, without needing another glove on top (unless I'm outside for very long periods of time without any activity). They're not great in high winds, but the wool in them makes them very warm otherwise. The touch screen pointer and thumb are very useful, and I've never had any issues using a small touch screen (like a phone) likewise works well with car head unit touchscreen, alarm panel touchscreen, tablets, etc. The size was a bit off I think: I usually wear a small and even with Outdoor Research Sensor gloves small fit me well - however with these I had to return the small for a medium. The fingers were too short for my fingers, but otherwise fit decently. I've had a few other glove liners and these are probably the warmest I have (although more thick), they fit well underneath Mechanix and Youngstown gloves, and give you the extra warmth you need to work down to 0. I definitely recommend these for anyone wanting a daily winter glove that's not bulky and works with touch devices.

Effectively keep my hands warm. Used them with sub zero wind chills wearing nothing but a thin pair of gloves!
