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.

Very easy to operate, clear picture, can turn the camera with your thumb and can record to laptop or phone using blue tooth. I wish I could have afforded this item years ago, but I guess it wasn’t this good of quality years ago.

Love the optional rotating head its a must in tight spots. Pic is clear, high res luv screen shot options. good reach def save you any mistakes pre drilling for pipes or wiring. Got extra warranty in case

I’m a hvac technician, it’s hard to find a camera that suits our needs.Other than the camera cable is a bit long, this camera is on point. With the adjustable head. Easy to operate and pinpoint cracks on heat exchangers. And slide through to inspect the evaporator coil, without tearing it all apart. Worth the money!

I am a mechanic and use this every other day. Works great. Good picture

is super tool to have. I'm in the automotive field and this tool does wonders with its camera and all feature that it carries. is like a owl head it can literally see around 360 degree with the touch off a button

I've used a stick style articulating borescope on my airplane engine for years. It finally gave up the ghost so I needed a new one. I wasn't sure how I would like the semi-rigid tubing versus the aluminum "stick" design of my old scope. I was very happy to find this style is actually easier to use around the engine / inside cylinders because you needn't have a straight path to what you're trying to inspect.My last one had to connect to a laptop to see the image. This Teslong unit has it's own screen and a memory card, both of which make it super simple to inspect in real time and save snapshots or videos to refer to later or send to your A&P.The image is super sharp and the adjustable LED light on the tip is great to get the best lighting, bright for dark surfaces or dimmer for reflective surfaces.The one key thing I've learned with this one is to keep my thumb on the semi-rigid tube oriented with the articulated motion of the head so I know which way the head will move with the adjustment wheel on the head. It took a minute or two but now is pretty intuitive to get the head pointed right at what you want to see, even when it's buried out of view down in the engine.Love this thing!

Great tool arrived in good time very pleased.
