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

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.

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of it, and in two years pick up whatever new tech hits the market, instead of dropping $500+ on something that’ll be outdated anyway and you’ll hate replacing.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.

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.

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.

Picture quality is great. Light at the end helps to see in dark locations. Good build quality feels nice in your hand. Flexibility is good and the articulation works very well and helps to see in some tight locations. USB-C charging and connectivity.

I have only used it once since purchase but it has exceeded my expectations. Perfect for me as a diesel heavy line tech. Excellent high quality image, easy to use and operate, not too much glare from the light and precise movement with the articulation. I would recommend.

This is a fantastic articulating scope that captures both pic & video. Nice clear images too.

Teslong two-way articulating borescope, this is the exactly the tool I needed in my toolbox, you can see everything, inside of your engine, under your refrigerator, I mean it is a very hand tool, it can turn up and down with the highest definition.

Works well and is easy to use. The image is clear, the probe is slim enough for tight spaces, and the two way articulation is very helpful. Build quality feels solid and it makes inspections much easier.

If i was to compare this to Milwaukee or other well known brand name tools this would blow then out of the water. The screen is impressive and the price point is amazing this is a must have. The seller has man options so buy the one that suits your needs.

Excellent value for money, picture quality is great, being able to control the camera angle is a huge advantage! Highly recommended this product

The moment when you open the box on this articulating borescope, your expectations are set pretty high. The packaging is beautiful, with a nice glossy box that opens to reveal a really nice storage case for the unit. Inside the storage case, the borescope is presented to you in a very nice fashion, with the screen facing up, the cable wrapped around it and a USB charging cable included in the box. In the top of the storage case is a zippered compartment that holds the manual and some other documentation, along with a few packages of alcohol cleaning wipes for cleaning it off. Using the unit is pretty straightforward. On one side there's a rubber gasket that conceals the charging port along with a microSD slot (which has a microSD card included). Along the face are a series of buttons including power, up, down, OK, an "M" button and a few other buttons that look like a "sun" (think brightness button icon). The functions of the buttons can be a bit confusing, since they seem to vary depending on whether you're using the unit or just trying to go through the menus on the screen. It's not super-complicated, but it takes a little getting used to and you'll probably find yourself clicking the wrong button pretty frequently. There's also a camera shutter button on the back side of the handle, in a place that's really easy to reach when you're using the unit (a nice touch, for sure). On the front of the handle is a lever, pulling or pushing it actuates a mechanism that causes the end of the borescope to articulate in a direction relative to how you move the lever. This mechanism works great, allow a long range of motion that can even let you look back on the cable attached to the borescope. When you're using the unit, the buttons on the face allow you to do a number of things, including turning on the LED in the sensor unit so you can have light in dark places, zooming in on what you're looking at and flipping the image (orienting the picture remotely can be challenging sometimes). One of the oddities of this unit is that if you flip the image then change the brightness of the LED, the image will flip back to its default orientation. I recommend using the borescope outside of a tight space (e.g. just looking at a room) to get used to how this works, since it can be confusing when you can't see something immediately recognizable. The picture quality is excellent. I used it to take a look inside the central vac lines in my home (for the record, yuck!), and I was able to get a good look with no issue. The length of the cable on it is not super long at 5 feet, so you are a bit limited in what you can do in some cases. The documentation mentions that it's IP67 water rated, which means resistant, but not water proof. I don't know if I'd trust it in a watery drain (certainly not a clogged drain). It'd probably OK in one that's draining slow, just to find a blockage. It also has a temperature sensor on it, and displays the temperature on the screen. It can be embedded in images, as well. Unfortunately, the readings on the temperature sensor make absolutely no sense. It never showed below 47 degrees Celsius in my home, and actually went up from there. I think the sensor is too close to the LED lights in the unit (or some other heat generating source), so gives a false temperature reading. If you're looking for a decent borescope that will let you look in tight spaces that are less than five feet from an access point, this will do great for you. If you need the temperature sensor, or want something that's good to use in flooded pipes, you may want to look at some alternatives.

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 !!
