    • Quality borescope at a reasonable price.
Was skeptical at first about this borescope, but once I received it and used it for the first time I was definitely impressed by it. Decent quality overall but very clear at about 1 1/2" to 6" which is going to be the range that you're going to be using this the most. I have been most impressed by the articulating head which comes in handy all the time with the ability to look 180° from the approach angle is especially useful. The light is plenty bright for use in most situations. The 6' cable length is perfect for most jobs. You are able to take pictures and videos with it which makes showing the customer the problem easier. One of my more recent diagnosis I was able to preform because of this was a cracked cylinder wall in a block on a engine that was having misfiring issues, being able to go into the cylinder, see the crack, take pictures, and show the customer all witout taking the engine apart is a huge gamechanger. Functionality is great for most automotive and maintenance work. Good value at a reasonable price. Would definitely recommend for anyone needing a borescope. ... show more

    • Excellent Borescope – Great Resolution, Strong Light Control, and Perfect for Automotive Work
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of it, and in two years pick up whatever new tech hits the market, instead of dropping $500+ on something that’ll be outdated anyway and you’ll hate replacing.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. ... show more

    • A must have for every serious technician.
Great quality. Clear image. Takes photos. Fits into any tight spaces. It's like having a helper when doing difficult automotive tasks. The long camera cord is great. Helps you inspect internal valve train components. Etc.

    • Good, but no charger included.
Good product, but does NOT come with a charger. The manual says it needs a 5 volt charger, but when I called the help line to find out what I needed to know to get a suitable charger, they told me that just any phone charger that uses a USB port would work fine. Those are , I believe usually 3 or 3.5 volt but they do work. I deducted a star for both the confusion, and not having its own charger. ... show more

    • Very high quality, high performing tool- best in class!
This thing works beautifully! The manipulation of the tip angle is smooth and easy, and it can turn around and look back at the hole it just came through. But what really surprised me is the depth of field. While the really precise focus is as described- and you can clearly see your fingerprints clearly in that range, the actual range that produces a clear picture is far larger. The first time I turned it on, I could clearly see people across the shop, even clearly read the clock on a wall 15 ft away. An exceptional benefit is the ultra-small diameter of the probe, only .21". Most articulating borescopes have 8mm or .33" cables. That not only reduces where you can get into an engine area, but it increases the minimum radius that the cable will bend to, and that limits the ability to reach and see what you want in many situations. Overall, everything works better than expected. The light, the resolution and focus and overall ease of use make this the best borescope I've ever used- and I do own 4 others. You won't be disappointed. ... show more

    • Image quality is top-notch
This is worth every penny for the quality of the image and the fact that you a take photos with it, and articulate the camera end. I was using a cheapo borescope before and this blows it out of the water, i wish i had upgraded sooner.

    • It was great, and then it wasn't...
It was great when it worked. I used it on two projects, and for what it did for me, I figure it was worth the money. That said, it held up less than 2 months. Failure point for me was the light. Camera still works great, but a borescope without a light is pretty useless. Replacing it with a different brand, and this time I got the insurance, which generally I never bother with. ... show more

    • Now I can see what's in there.
I have thought many times about needing a borescope for one thing or another. I seemed to always get by without one. The stop plug on my bathtub got stuck holding the water in my tube and would not come back up. I decided its time to get a borescope. I did some quick research and decided on the Teslong Two-Way Articulating Borescope, 5.5mm Slim Probe. There are many to choose from. I liked the idea of the articulating camera and the .220 size. I was able to get this camera down the overflow to see the plug even past the lever, cover and linkage was still attached, but loose with the two screws taken out. I even managed to work the camera from the drain in the tub and work it 90° to see the stop plug in position. Bathtub drains are a very sharp turn. I could see the plug was most likely stuck due to hair in the drain. Knowing this, I knew I needed a paracord to wrap around the pin holding the plug lever to the linkage and give a good pull to get it out. It worked because I could see what was needing done. It also made getting the hair out of my drain much easier. The tool seems well made. The screen is very clear and the 5" size is plenty big. If I have any complaints, I would say the buttons could be marked better to see. The buttons are dual purpose, depending on what mode you are in, so a card with a cheat sheet as to what the buttons do would be handy. I highly recommend this tool. I'm sure i will find plenty of uses for it. I highly recommend it. ... show more
