This hand warmer works instantly and seamlessly (as long as you hold the button for 2-3 seconds, which took me embarrassingly long to figure out). I have cold hands and feet already but the approaching winter makes me worry about cold, sore hands. I love that this is so portable and is ideal to carry with me! I will definitely get my use out of this throughout the fall/winter seasons!
