What makes it one of my indispensable helpers currently is solely their construction: attached to the tip of a thin electric Einziehrohrs it allows me to throw glances in a plasterboard ceiling hollow - namely through the milled holes of ceiling spotlights. They put me in a position subsequently electrical wires in your circles by the stud frame through having to tear anything. After a little practice, I am now in a position - like a surgeon of endoscopically - using, if necessary, the pipe moored simple tools (cutter, hook) to separate fortifications and to take cable and to use.
For this, and for similar tasks (eg exploration of pipes and other hard to reach cavities in house), the camera is a blessing, and the image quality is sufficient. Since it also has a sufficiently robust for my purpose makes impression (watertightness could and I did not try), and is not expensive, I give her despite the obvious weaknesses full score: good enough is just enough, everything else would be a luxury.
Note that the flexible cable is not suitable to introduce the camera, it is too soft. "Rappel" to watch in a shaft is possible, but if you want to run or move the camera in a different direction you have to make it firmly to any thin, flexible rod. A 16mm electric insertion tube has been proven to me, it must be kept strong enough to the camera floating freely about 2m wide, and yet still so flexible that I can ride light curves. I could also more pipes are plugged together and so still pass if needed, but the road must be straight, more or less, "around the corner" does not work this construction. Need to explore labyrinthine cavities can come up with something else after what ever can be pushed therein, or any steerable vehicle build which may carry / pull the camera. In this respect the 10m USB cables are sized luxuriant - it is unlikely to give applications (except down, or possibly with a piece of hose or electric cable as an aid in a tube) where you can run the camera so far.
