I bought this remote camera to evaluate a blocked sewer line on an abandoned building that would be put back in service. (The cost to buy this camera was about a third less than the cost to rent a sewer cam for 4 hours, and a fifth of the cost to hire a plumber with a scope. )As I was able to clear and flush the line (with a garden hose and nozzle), I was able to see well enough using this camera to know that the blockage was being cleared and that the sewer line was intact. I could see that the line was not collapsed, once the debris was flushed.However, since this was a cast iron pipe, coated with a century of iron scale, i was not able to see detailed condition of the cast iron.The camera Cable is not well suited to "push" through a sewer by itself. I first tried attaching it to an electricians fish tape, but that also got hung up on joints and turns. I then taped it to the garden hose that I was using to flush the pipe. That allowed the camera to move down the pipe and see reasonably well. For the final look, it worked well to push the hose the full length of the camera cable, then record in one continious run as I pulled the hose and camera backwards out if the sewer. Luckily, the camera cable 16 foot length was just enough for me to get to the sewer line hookup to the sewer main, but length is a limit.The picture quality is pretty good, considering. The light does a good job, with juat a bit of "bright white light wash-out". The easy ability to switch between forward and side cameras is useful.The one thing I haven't tried yet is to download the video - you can see it pretty well on the provided screen. Now that I own it, I'm looking forward to funding other uses
