Really wanted a cool case for my cool G11, and thought this one looked best. It's obviously a cheaper version of the Canon one, which is considerably more, and I have to say with this in mind it's brilliant. Being brutally honest, you can tell that it's not an official product, as some of the edging is slightly messy, and the outer cover is just slightly sagging on one side, but these are minor criticisms.
Overall, it looks cool, protects the whole camera, and allows for the official strap to be used, and also comes with another strap in the same brown leather. It even smells cool.
