The picture quality was great making it easy to see what you are looking at. I was worried that the camera would only see right in front of the lens but I could also see further out and the light was bright enough which was a big plus. The side view lens helped seeing to the side if needed while moving the probe forward. I bought this Endoscope camera to help me put in a light running electrical wires from ceiling to wall on a two story house. Cutting small holes in drywall and looking before drilling holes saved me as ABS piping, and wiring were in the wall and could of become a major job and added cost if I had drilled thru them. After using this tool I only cut where necessary with smaller holes in drywall which makes it easier to patch. One thing I noticed when inserting the probe into the wall you didn't know the rotation of the image you were looking at. I used tape and marked the tape with a line so when I inserted the probe into the wall I knew left was left and right was right. Very happy with the way this job turned out. I also used the Endoscope to look at the jets in my inground spa. I wanted to find out why some of the jets were not working so I wanted to remove them for cleanout if necessary. I wasn't sure how the jets were to be removed so being able to see inside the jet tube I could see that a plastic nut was there and could be unscrewed. Crazy how far back the jet were in the tube but knowing your not going to damage anything and again could be costly for the DIYer if you cannot see what your doing. This Endoscope is better than the one my buddy got and paid more for. Very happy and glad I got this item. It has already paid for itself.
