I went on holiday during the Xmas break and it was snowing where I was. Obviously I came prepared with jacket, hat, gloves etc. I was a bit concerned about turning my ATC-2K cam on and off though. I didn't want to take my gloves off just to do that. Turned out fine though, I just listened for the beeping noise it makes for on and off. Also, the manual says to use a heat pouch it sells, or is planning on selling, in cold weather along with lithium batteries. At times the temp was below freezing and my cam worked fine without either! There was one time when it was a bit slow though so I took out the batts and held them in my hand for a minute to warm them up. It went back to its normal speed after that. It's a plug and play cam so no need to use a CD to install, just the USB cord. The video quality obviously isn't as good as a normal video camera but that's expected as it's designed for extreme sports. It's also a handy size, fits into my pocket easily and only needs 2 AA batts.
