This is my first video scope purchase, so I don’t have anything else to compare it to, but there are definitely some things that I noticed about using it that might be helpful to others if they are going to get this unit.I own an air duct cleaning business and I purchased this unit to do a video scope for one of my clients of air ducts to look for any kind of deterioration, damage, or holes in the ductwork.PROS: Very affordable in comparison to other video scopes. The video screen unit is extremely easy to use (only a few buttons, but right out of the box you plug in the cable and hit the power button and it’s ready to use). Has phenomenal HD picture quality and can both take pictures and video. Seems to have a good battery life (so far). The video cable is extremely long (50 feet), and I was able to go deep into the ducts. A lot of the other products of this type had a cable of about a maximum of 15 feet.CONS: Video cable is incredibly stiff and doesn’t maneuver well in air ducts and I imagine it probably doesn’t maneuver well in drain pipes either. The camera is not positioned well in that it’s on the side of the camera unit instead of on the end. If the camera was on the end (which I think would be a much better design), you would be able to see a lot more than just the sides of the duct or pipe. I found myself having to reposition and re-feed the cable several times into the duct to see what I wanted to see. And since the cable is so long and stiff, it can get easily tangled and it’s kind of a pain to put away.I was able to get the video scope job done (my client was generally satisfied) and having this unit came in really handy when one of my air compression hoses got stuck in a return vent on another job. After a several minutes and re-feeding the cable in and out several times, I was able to diagnose the problem and fix it. I was extremely happy that I had purchased this unit because it probably would’ve taken much longer to diagnose the problem had it not been for the video scope.If you are planning to use this for the occasional home project (for the DIY type), to get eyes on a tight space that you can’t normally see, or a clogged pipe, then this is a good tool to have. If your business is professionally scoping drain pipes, ductwork, or electrical wires, then this unit isn’t for you. This unit is for consumers — not professionals.
