3 in 1 Inspection Camera with Light, HD Inspection Camera Borescope, IP67 Waterproof Borescope with 6 Adjustable LED Light Snake Cable USB Adapter for Android Phone PC(1 M)

I bought this, I have an android phone, the app didn't work, now it's in the junk drawer.

Couldn't connect to app using my android Samsung phone

I recently tried out this USB borescope, and honestly, Im incredibly disappointed. I used it once just to test it out, and then it stopped working entirely, which was really frustrating. The app that comes with it is not great either; it's very clunky and not user-friendly. The buttons are tiny, making it hard to navigate. The cord and gooseneck feel flimsy, which doesn’t inspire much confidence. The light isn’t bright enough, and when the camera was working, the quality was so low that I could barely make out what I was looking at. On the plus side, the included accessories worked well, but that’s about it. I can’t help but feel like this product is a waste of materials and resources, especially after receiving it in such a disappointing state. I wish I could return it, but unfortunately, that’s not an option for me. Overall, I wouldn’t recommend this borescope.

Won’t fit a 22 barrel. But might be usable for bigger bores. Picture is very clear. Can record operation if needed.
