Review on Waterproof Winter Gloves for Men & Women, Balhvit 3M Thinsulate Thermal Gloves, Breathable & Touch Screen Compatible with 5-Layer Protection by Robert Sorrells

They didn't fit - there was a lot of space between the insulation in the glove holding the fingers and the outside of the glove. I wore them for 20 minutes in 35 degree weather to walk my dogs and my fingers were freezing. They are unlikely to work at a temperature of -30. The material looks and feels VERY CHEAP - it's tough, unforgiving and you can't use the "touch screen" because the material is so flat and hard. The instruction card is written in broken English - and you get a $10 Revain card if you give them 5 stars (which is why it has such a high rating). You get what you pay for - it's basically a $10 pair of gloves from the store. you have been warned 🤷🏻‍♂️
