Teslong Two-Way Articulating Borescope, 5.5mm Slim Probe, 5.0'' Industrial Endoscope with Light, 5FT Flexible Snake Scope for Automotive, HVAC & Mechanics

So I bought this to suss out an oil leak. Found the oil leak, a leaking timing chain cover in the rear of the engine. Bummer. However, this awesome bore scope really saved the day in terms of me NOT having to pay a mechanic to suss it out. Since then I have used it almost weekly to suss out other issues, including home problem (found a dead mouse stuck in a vent pipe, damn we could have died from the backed up gas). So really, all I can say is not only has this bore scope paid for itself multiple times over, but maybe even saved our lives. So if you need one, get this one, extremely dependable and accurate and makes really crisp clear images and video. Well Done !!

Great articulating borescope and a very good value for the price. The 5.5mm camera is very slim, which allows it to fit through almost all spark plug holes and makes it great for checking cylinder walls, valves, and other tight areas. The picture quality is good, the camera works nicely, and the articulation makes a huge difference compared to a normal fixed borescope since you can actually look around inside the cylinder instead of only seeing straight ahead.Overall, it seems to hold up well as long as you use it properly and don’t abuse the articulating end. My only complaint is that I wish they included attachments like a hook or magnet for this slim model like they do with some of the thicker models. For the price, though, it’s a great value and much more useful than a basic non-articulating borescope.

This borescope is way better than I expected for the price. The resolution is excellent, the light adjustment is spot-on, and for automotive use it does everything you actually need. Don’t get fooled by all those “360° rotation” gimmicks on expensive scopes — none of the cheap ones truly look backward a full circle anyway.This one realistically gives you about 180° backward view, and that’s more than enough to inspect valves and see exactly what you need inside the cylinder. For automotive work, this scope is absolutely enough — you won’t miss anything.No need to overpay hundreds of dollars. In a shop environment, a scope like this usually lasts a year or two under heavy use. And honestly, that’s the smart way to do it — buy this one, use the hell out of it, and in two years pick up whatever new tech hits the market, instead of dropping $500+ on something that’ll be outdated anyway and you’ll hate replacing.Great tool, great value, perfect for real-world automotive diagnostics.

excellent image quality. easy to manipulate the camera, long line for deep cavities and hard to see locations.

Great picture quality. Fit into tight places inside the heat exchanger. I wish it had rechargeable batteries instead of the unit needing charged
