Idiot-proof
Nothing overly complicated about this thing . . . pull the battery saver tab, push the button, and if you are dealing with the right Canon camera (and I was), it works, period. The case that it comes with attaches nicely to the existing camera strap, so in just a very few minutes, I had a new capability for my camera that I need when taking tripod photos. I take photos in archive vaults where flash photography is not allowed, so the tripod is very necessary. The less I touch the camera as I am taking assembly line photos, the better. This fits the bill, letting me take photos without ever physically touching the camera, potentially screwing up centering or focus. Great gizmo for what it does.
