Does anyone try using hand warmer before?!

Question: Does anyone of you feel that your hand is cold due to cold season or simply powerful air-con in the office? Have you try using hand warming product such as USB Infra red pad: http://www.usbfever.com/index_eproduct_v...

If so, please tell me which product you use and whether its good? Thanks alot.

idk about those but get handwarmers at *****, or walgreens they work amazingly and they are SO much cheaper and the last for 6 hours just shake them and they get warm then you throw them away when their done.
also there is feet warmers, toe warmers and back warmers.
