Review on TriPole Hand Warmer Rechargeable 5200MAh Electric Handwarmer Reusable USB Pocket Hand Heater Portable Power Bank, Warm Gift For Winter Outdoor Sports Women Men, Double-Sided, Fast Heating, 2 Levels by Daniel Hicks

I like this product, it does help keep ke warm. I work overnights and it's nice to carry around my personal warmer without having to heat up the whole department. It does get hot even on the lowest setting so I tend to turn it off and on. I think it said that one charge lasts 8hrs (I could be wrong) but i find it doesn't last that long for me but it still does what it says. Im only giving it 4stars coz 1) it gets pretty hot 2) it doesnt last 8hrs on one charge. But i really do like this coz it's portability, convenience, warmth, and price
