I've got some holes in my walls that I wanted to do some investigating into. I have a cheap wifi "camera on a wire" type device, but the camera is low quality and it's very hard to control once it's in the wall. This scope has two features that make it far superior. First, the directly of the camera can be controlled in a 180 degree arc with a knob on the handle - no matter how far in the hole you have it, you can point it where you need it. Secondly, it has a camera looking out the side - sometimes you don't need to see what's in front, but to the side.

The picture quality is excellent, and the 5 inch screen makes it easy to see what's going on. The light is bright enough to fully illuminate a dark space. Being able to see both camera angles at once is also nice, but I usually do just pick one or the other.

The included case is also very nice and sturdy - when you're not using the scope it will be well protected. The wire it's on is fairly stiff and will hold whatever shape you put it into. The only negative I have to say is that is is only 5 feet long. That's probably a practical limit to be able to control the head by wire, but it does limit some of the applications (like going deep into a pipe to find a blockage). Still, for scouting out ceilings and walls, it's perfect.
