I own a Canon PowerShot A550. The Gorillapod screws into the camera securely. The downside is that on the Canon (and Sony Cybershot DSC also) the screw is not in the center of the camera, but off to the left (if looking at the back of the camera). This off-set causes the camera to "slump" to the right because it's off-balance. To make matters worse, the button to take the photo is on the right, so if you get the camera to balance on the Gorillapod, you still have to press the button to take the photo, which causes the camera to slump then to the right.
The 2 ball-like connectors that connect the camera to the 3 legs on the Gorillapod don't seem to have enough resistance to keep a small camera like the Canon in place.
My mother-in-law has a Sony Cybershot DSC which is small enough and light enough to not slump, so she will probably be getting the Gorillapod to use with her camera.
I love the idea and was excited to get it and try it out. Doesn't work for me like I expected and my point and shoot isn't big at all. I would have thought the design would have taken into consideration that the point and shoot cameras don't always have the screw hole in the middle of the camera.
