iCan webcams at Canada Computers

Has anyone tried the iCan brand webcams from Canada Computers?
I'm looking for something basic for very occasional use (a couple times a year), and the price looks very good:

The specs for all of them are basically the same... 2 MP CMOS sensor, 720p/1080p resolution, and glass lens.

I think this would be my second choice if I don't get an iCan webcam:

But I'm looking for the best bang for the buck.

Any feedback would be appreciated.
