I am always the photographer and never in the shot, so I got this extender. Closed, it is compact at 8" and easy to carry in a small camera bag or in your back pocket. I carry it in a flash light holster. haha, it looks like a collaspible baton (totally illegal in calif.)
I use the extender for self portraits and shooting over crowds. The locking ballhead is strong and useful. The extender doesn't twist lock, which would come in handy if your camera's tripod mount is off centered like with my Panasonic DMC-LZ7. The camera is a bit heavy and if I don't hold the extender at the right angle (twisting to the right), the extender will twist to the left. It takes a bit of practice to keep the camera balanced after extending it. Right now, the sections (there are 5 of them) are still new and tight, so the extender doesn't extend by itself but there is a bit of twisting.
It also can double as a monopod, but why would you need a monopod for a point and shoot unless you are shooting in low light with a slow shutter speed. In that case, I would just shoot at a higher ISO.
If you have one of those ultra, light point and shoot cameras with a center tripod mount, you will be happy with this extender. So get one and get yourself in the pictures!
