Have the camera ordered to see the cause of our ever-clogged kitchen drain (diameter 5cm). The place sits somewhere in the floor, our spiral helped only briefly. So camera connected to a laptop and going. In Bright had zunindest blurred images, so from the pipe - one sees absolutely nothing, whether with dimming light or very bright, in the price actually realized, that can not give the appearance, but I wollts a try.. And because the camera has no leadership, the lens scars probably always on the pipe wall along, because you can not see anything. Conclusion: not to be used for this purpose, but I can imagine no other purpose in which they could bring. I have the camera sent back and 99 for professionals ordered, what the hell, now everything works!
