I REALLY loved my hand warmer, I think I've bought 2 or even 3, but unfortunately they don't last as long as I'd like. they just stop charging at one point which is such a bummer as it's been less than a year. I got mine on Amazon and they're no longer available there or even here, so I couldn't repurchase if I wanted, just wish the ones I have would work. When they did work they were great, they warm up super fast, last long, and even work as a portable charger which I LOVED and am not able to find with other hand warmers.
