StickPic

I have one and like it a lot. Particularly for a solo trip, much better "selfies" than extending your arm. Used it when shooting my avatar. Weighs 0.4 oz.

I keep mine on a tiny biner hooked onto the zipper pull of the hip belt pocket where I keep my camera.

The small black tightening ring can come loose and get lost so tighten it down good not just when using on your camera but when storing as well. I lost mine, they sell a replacement for a few bucks.

"There’s not much to it; just the little piece of PVC with the hole drilled in it, and a plastic toggle to secure it up against the bottom of the camera"

The StickPics I own are all made of delrin bodies, with CNCed aluminum camera nuts. I wouldn't normally nitpick about a point like this, but the actual materials used for the product justifies the cost they charge a lot better then "PVC and plastic" :)

Since phones cameras have been coming such a long way I find myself leaving the camera at home these days in lieu of just taking the phone. Really wish there was a StickPic type of attachment for that.
