Review on Stay Warm And Connected: BRIGENIUS 5200MAh Rechargeable Hand Warmers With Double-Side Heat Therapy And Phone Charging Capability – A Perfect Winter Gift! by Devon Leach

I ordered two of these hand warmers and one unit would not charge completely. Sent it back for replacement and new unit arrived within a few days. Used both hand warmers when needed for about 3 months then one hand warmer quit charging and will not power on. Haven't decided if I will waste my time sending it back, I think I will do my research and find better quality hand warmers that I'm sure will cost much more than I paid for these.
