I tried to use it today while snowboarding.
It kept turning off on me.
It was 20 degrees out so it wasn't that cold. The product says it will work in 17 degrees weather.
Never did get it to work today.

I ordered the camera and didn’t get a reply from the company (GSM). After a week I called and they said it was being processed, I asked if I will get an email when its shipped and was told “we get hundreds of calls a day and I can’t remember your address to email you when it ships, call back in a couple days.” I was speechless. After finally getting the camera I quickly became very disappointed with the quality of video. On a bike the picture is very wavy and bad quality. Going to bright light from dark takes a while for the camera to respond. Rechargeable batteries will not work. Only lithium ion work and they are around $10 for four batteries. That gets you 2 hours. If you are going in water you have to buy an extra case. Very poor camera and even worse customer service.
