These hand warmers are excellent. Time to stop buying those wasteful, expensive, and expiring disposable handwarmers.
This hand warmer is amazing! My hands are constantly cold and I've tried all sorts of products to help keep them warm but nothing has worked until now. I charge the hand warmer every night with a standard USB charger and the next day, I have hours of warmth. I've already given hand warmers as gifts to several cold-handed friends and family members and they're loving it as well.
Better than the pictures and more useful than described. This little gadget is way more than a simple hand warmer. The uses are endless
