Warmers heat up quickly, warm enough to maintain heat. Heated with Velcro, can be attached to other gloves. In principle, in the cold winter, in the long hikes to nature very helps.
Heating pads are just 5x7cm carbon film resistors (see photo) stuck to the inside of the glove with Velcro, so they can be removed for washing and substituted if broken. No heating on the fingers. I got 2 pairs, each glove draws 0.2~0.45A so some may heat up half as much as the others. Fingertips are free, so the gloves fit both long and short fingers! Also you can type a keyboard normally, and use the fingerprint reader and touchscreen on your cellphone. Use the warming pad on the back of your hand; if you use it at your palm it will crumple up and break. You can feel a warm pleasant glow from the pad, but it's not enough to heat up a cold hand or cold fingers. Overall a convenient glove to use indoors - for outdoor use I still prefer full leather gloves and a touchscreen pen. For seamless mobility I strongly advise to run the cables up your sleeves and carry powerbank on your pocket. Nice idea, worth trying for this price.
Heating works the length of the wire a little more than a meter came into the hole still Moli I was not enough
