iPhone boresnake

[Playa]

Anyone use one of these? Or one similar? Clear enough or is 2mp not clear enough for fine detail down a bangstick pipe?

Problem is that the camera is 8.5mm in diameter. So it will be big bore only.

I bought a couple of those and they pretty much suck... sent 'em back.
They're way too big for most rifles and the image quality is junk.
Also they usually require you to download some junky app that crashes all the time.

There are smaller ones I've ordered but they really don't focus on things that close..
