Though advertised as a sewer inspection camera, I use it for inspecting welds in pipe/tubing. All in all, it works great for that, with some limitations. Picture quality is quite good, even though it can be a little difficult to get a good view in focus, sometimes. Again, this is not the camera's intended purpose, so no fault there. The side views are a great bonus, and the lighting works surprisingly well, compared to some other cameras I've tried. The cable is rigid enough to push the whole length through a pipe, even with a couple of bends--just be mindful of the radius. In a sewer line, I suppose this won't be a problem. The screen works quite well, although I've only tried it indoors, and not in bright sunlight. The included micro SD card is adequate, but you may prefer it different capacity card, or just a different brand. That said, you can easily download pictured from the camera with the included cable, or simply remove the card to download the pictures. The cable makes it easy to charge the camera, although I haven't taken the time to check how long it takes to fully charge, nor how long the charge lasts while using the camera--I use it for short periods, about 30 mins at a time. Bottom line - for DIYers, or even limited professional use, it's a good camera for the price. It's worked well from 3/4" - 4" stainless tubing, and even running it behind a wall, or two. I imagine it'll do just fine in a drain or vent pipe at home, or just to inspect behind walls, or other things. The only downside that I can think of is that it can be cumbersome to store in the included case, so don't unroll the whole 50' if it's not needed. Unroll the length you need, and keep the rest coiled tight with the included straps. Maybe get some extra velcro straps to secure the rest, when you coil the cable to store it.
