We bought the Kidizoom Camera for my son's 4th birthday and bought the case to go with it. We don't like the single shoulder strap, a rucksack type arrangement would be more appropriate, but my son loves putting it diagonally on over his head and one shoulder which negates the problem of it sliding down his arm.
It's big enough for the camera, the leads and other bits and pieces. It's also reasonably well padded to shield the camera from some of the worst knocks that it might get.
Overall, we like this case and recommend it to anyone who has purchased the kidizoom camera.
