Great hand warmer for the price. it is a bit bigger that I thought; roughly the size of a hockey puck. Had to charge it up before I could use it. It takes about 2-3 hours to fully charge using a 5V 2A power adapter (I used the Samsung charger that came with my phone). Battery life was about 4 hours? I lost track of when I had it on and off since this thing gets really hot. It only has two heat settings with low being about 50 degrees Celsius and high being 60 degrees Celsius. Would have been perfect if the low temperature was a bit lower and had more temperature setting.

J'adore ! Il tient bien dans les mains, la housse de transport est douce et pratique. Il chauffe bien et à 2 niveaux de chaleur. Pratique pour les sorties extérieures tant pour les adultes que les enfants.

Garde le mains au chaud. Bonne pile de secours pour recharger le téléphone.

Just warm enough on the first setting. It's very popular in my home.

Le produit que j'ai reçu ne fonctionne pas, même après plusieurs heures sur la charge, le produit ne fonctionne pas.

Purchased as gifts for others, and they LOVE them! The concept of hearing up the area around a Li-Ion battery is questionable, however...
