NTG200H Focus and Fold Rifle Borescope with 4.5-inch IPS Screen

I love the fact that this can be broken down to half and stored. I also love the adjustable focus feature. I don't like the construction. It is weak at the joints. Mine broke at the focus joint with the second use. Also, the threads for the mirror to attach to were very gritty. Called teslong, and they are sending me a new camera. We will see if the new camera works better.
