Im currently borrowing a friends £10 from china one...
For a tenner, its ok, but the depth of field is not great. Although, if you shoot it across a bright room, you get a grainy full view shot on the screen, when in a dark wall cavity, theres not enough light (it has led lights built in) so you can only see whats right in front of it. Kind of like when you see those deep sea submarine shots of old wrecks etc.
So, i guess its more a light issue, than a lens issue, but thats the way it is.
It is, however, water proof etc. and does solve problems that would be impossible otherwise.
Later today, im to stick it down a soil pipe that i found under some old concrete, to see if its still connected to the sewer.

I bought a cheap Chinese USB inspection camera off Ebay a couple of years ago to use on my laptop, quite impressed with it for £13 delivered! Similar limitations as noted by julianf above but the lens on mine is focused for close range.

I recently been playing with a supereyes b005 inspection microscope for use on my cnc mill to centre with, off amazon. It goes to surprisingly long distances on its lowest settings and has built in adjustable led illumination.
It also goes to x20, and best of all it works in linux (it presents as a usb webcam and use the uvc driver), which as my milling machine runs linux. I can just click on the camera tab now in axis gui and do the live centre or edge finding without having to load up a edge finder. But for the rest of the world it comes with windows drivers. At 20x the image is very clear. Its a manual focus setup though. Ive found the adjustable level of led lighting on the thumbwheel means I can turn the lighting to match the object being inspected as too much with bright steel for example makes for equally a poor image as not enough. It came with a little tripod too, but I threw that away and made a mounting instead so no idea how good that is.
I have the drain snake inspection cam style unit also, the first time I used mine stuffing it down the sewer revealed it didnt have the camera glued in place behind the lens and twisting the wire caused it to twist on the end of the wire and now its cock eyed and cant see anything, and to fix it, I would have to break all the seals, and I bought it because it was factory sealed...
