NTG450 Rifle Borescope with 4.5-inch HD Screen

The picture is fairly good and you get a better view of things using the side mirrors. Carbon rings and steel cracking come into view when present. The picture on the included screen works better than hooking it up to your phone app. The enclosed instruction book could be a little bit more straight-forward. I took one star off since there was a bit of difficulty in the mailing process, but that was straightened out by customer service Otherwise this is a good deal on a worthwhile item.

Wonderful item. After a few weeks the camera ceased working. I tried to purchase another probe / camera but they don’t seem to be available so I was forced to purchase another camera from a different brand. Disappointed that I couldn’t purchase a Teslong replacement probe camera.

It arrived faster than expected
