I have had this camera for about 6 months and love it as much as day 1. The picture are great quality and don't think any higher resolution is needed at least for automotive use. The pics I attached show how easy it isolate cause of engine mechanical issues. Much quicker than a leakdown test (although like a noid light, easy to tell a failure, but could lead you to false pass in some situations. My only recommendation to other techs would be to possibly consider spending the extra money for the 0.24" diameter camera. I have the 0.33" diameter and even though it works in most spark plug holes, it is very difficult to fit in some of the Fords with the smaller diameter plugs. It would probably be worth the extra $60. There are times when I felt a triple camera would be better, but the articulating triple cameras I have seen are near or over $1000. I might get the Teslong triple as an addition to this and still be way under the 1000 price point. The app is extremely convenient and allows you to connect to your phone to make taking pictures to show the customer much easier. Also allows you to set camera down and view from a remote spot such as when viewing for piston coming up on TDC when rotating crankshaft. As with anything else, I'm always learning new ways to use this camera but it is a real timesaver and leads to more accurate diagnostic results.
