This Endoscope saved me a lot of money the first time I used it. After a kitchen renovation job was completed, we discovered that there was a leaking waterline to the refrigerator as we turned on the supply line (although said line tested good before the walls were closed up). Water was pouring from the ceiling downstairs. We had no way of knowing exactly where the leak was within the walls that the line was run. I pulled out the refrigerator from its cavity as there were no tiles within that area. I then cut a 12" x 12" hole in the wall and put my Endoscope into action. The sturdiness of the flexible cable allowed me to send it through the wall cavity while watching everything on a perfect color screen. I found the leak 9' away which was caused by nails from affixing baseboard from an adjoining bathroom. I knew exactly where to open the wall to make the repairs, without having to remove a 10' section of cabinets, countertop & tiles which would have been very costly. To top that off I was able to see a socket that I left in there before we closed up the walls. I was able to retrieve it using the magnetic attachment that came with the kit. It was a win win situation for me. The dual lens & ring lights are magnificent. I definitely recommend this inspection camera to anyone in construction or any mechanical field. It's your eyes & hands in seeing & retrieving stuff in the impossible or hard to reach areas. As a matter of fact, I think every home should have one of these. It will be worth it.
