USB Borescope 3 in 1 Semi-rigid Type C Endoscope Inspection Camera IP68 Waterproof Snake Camera with 8 Adjustable LED for Android, Windows & Macbook OS Computer,16.5FT(5M) - Skybasic

Its functional, that's about the best I can say. Finding an app that works well with it was a problem. Image quality isn't great. USB connection is loose so trying to keep it connected to phone while fishing the camera isn't easy

The LED light on the scope is very bright and the magnet attachment is very convinient. I hooked it up to my tablet and was able to fish out a loose bolt from my AC duct.
