Teslong Two-Way Articulating Borescope with Light, 5-inch IPS Endoscope Inspection Camera with Articulation Head, Automotive Mechanics Fiber Optic Scope-0.33inch

I watched tons of review of different endoscopes before ordering this one. Comes in case, great build quality, great picture quality, ease of use, could be cheaper, but if you are ok paying extra $ - you won't be disappointed. Really functional, has an SD card and ability to record photo and video. I got a longest camera cable length and you can use it for any occation, car repair, vent checks, etc. Battery life is good.

It’s amazing and has helped with a lot of different jobs that I have worked on - making them a lot easier. I’ve treated this thing pretty rough and it’s holding up really well. The ability to easily invert the image is very helpful as well as taking photos and videos.

AMAZING !!!! absolute game changer this makes any internal diag so easy. I use this all the time for internal engine inspection valvetrain, HVAC actuators, looking for leaks in tight places, checking for bent valves, checking for carbon buildup. Checking timing components and timing chain tensioners. If you dont have this camera for inspections your in the past and your wasting time. As a service technician working on cars everyday this is a must have I dont know how I didn't have it sooner. The price is amazing too Tool trucks sell this setup for 5x the price

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.

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! Update from my original review. I bought this in Nov 2023. In early May 2025, I pulled the borescope out of the toolbox to do a valve inspection on my engine and the borescope wouldn't focus on anything (near or far) and had an odd halo / haze over everthing. I contacted the Teslong support email describing the problem and asked for any advice on how to fix the issue. They responded within a day... +1 star (from my original 5). They asked for a few photos of the issue, an image of the receipt, and the original order number. I submitted that and a day later, received an email saying a new one was one the way! + another star... Is there a seven star rating on here?
