Not gonna lie, I was slightly skeptical because of some reviews. I have only had this tool for a few days, but I have used it several times with no issues. I have rental properties that I will need this camera for, but also some other properties I'm doing construction work on to get a better idea of what's causing some flooding and settling issues. When running the scope through a stretch of underground drain pipe, I was able to find the source of rain water backing up, as there was debris stuck in the pipe. Without this tool, I would have had a heck of a time finding the source of the problem. The camera showed me stuff was in the pipe, and the locator told me where it was. And on another property, I have some drain pipe that is buried that I had no idea what direction it went. Again, the locator helped me figure that out as well. This is the first time I've ever owned this type of tool, so I have nothing to compare it to. However, the short time that I've had it, it has served me well and and saved me from doing a bunch of digging. I have not had a reason to request customer service, as it's working fine for me, so it gets 5 stars from me thus far.
