In subzero weather driving the Polaris to clean the snow off of the driveway or going shopping these are great even without socks they keep my feet toasty warm. I only wish I could have found them for my husband when he was doing chores and digging us out of the snow on our farm all those many long years. If your wondering how long they last after two hours cleaning the driveway I came in and removed them from my snow boots and stuck them in my slippers and they kept my feet warm until I went to bed about 8 to 10 hours after I opened them. I cant see living up here without them ever again.
Looks decorative (placed an art statue above it). Sturdy as most hotel safes but is larger than those. Battery life is great (10 months so far). Stores many finger impressions in case you roll your finger or apply more pressure. Beeps loudly when you open (good or bad for burglars) and keeps on beeping if you leave it open more than a minute (good if you have kids around).
I love to snowboard, but my feet start to hurt about 10 minutes in due to the cold. I've been snowboarding for 8 years, and for the first time, my feet don't hurt if I put these warmers in my boots! They work instantaneously and last for my full day on the mountain! WOULD HIGHLY RECOMMEND!
