BIUYOHand Warmers Rechargeable 5200mAh Electric Portable Pocket Hand Warmer/Power Bank Upgrade USB Portable Charger Double-Sided Heating Safe Heat Therapy Pain Relief Best Winter Gifts

I purchased the above product to use as a handwarmer and unfortunately I wouldn't recommend it at all and think it should be withdrawn from the market as it badly burnt my fingers while I was sleeping. I woke up the following morning with huge blisters on two fingers, which burst, and I have been left with two very raw fingers which are very painful.

Ibought it for myself, because my hands always freeze. The hand warmer heats up very quickly specially when level 3, it is so convenient and pleasant to use it.Small size allows it to be worn in the feed.Work really well. Easy to charge and long lasting.Convenient hand warmers will keep you and your loved ones warm this cold season! Love it!

It stopped working a week after I got it. I thought it was an issue to do with charging but it presented itself as being fully charged.

Excellent would highly recommend!

Very nice little hand warmer. Good quality, can get really hot, my mother in law loves it. Would recommend it to everyone.
