5MP Auto-Focus Endoscope, Teslong 3rd Generation USB Borescope with 5.0 Megapixel Inspection Camera, 16.5ft Waterproof Semi-Rigid Cable & Adjustable Led Lights Probe for Android Phone Windows MacBook

I bought this unit after I could not find the endoscope I had purchased about a year ago. This scope is far better than the one I couldn't find, and if I do find it, it's going on Craigslist. There are two primary reasons. One - the autofocus is works very well. With my old scope, I had about a 2 inch focal length. This means that one can only see about 2 inches away with clarity, making it difficult to gain an overall view of your search area. With this endoscope, I can look at objects as far away as 15 inches and that means it's possible to see the overall scene before coming in for a closer look. For example, I was looking for a collapsed spot in a 4 inch sewer line. I was able to clearly see the entire sewer pipe as I inserted the scope, then was able to take a closeup look where the pipe had collapsed. Two - Very good image quality, much better than my old scope. I don't know what they mean by 5 MP but the resolution is more than satisfactory. I gave a three for ease of use. First, the endoscope is very stiff. I understand that it needs to be stiff to push 16 feet of scope wherever you want it to go. My old endoscope is the same way so this is not a product complaint, just noting that it can be challenging to get this to go where you want if there are curves and bends. And second, while the Android software works, you have to download an ad laden app, then apply a code so that it works without ads for this product. I would much rather see an app in the store, ready to download, without getting a third party app. For Win 10 the camera app that comes with the OS works fine although it doesn't offer many image manipulation options. I've not tried the available Windows apps since the Camera app met my needs on my Surface tablet.

Been searching for this since I bought my first endoscope (another maker) which was fixed focus about 1/2 inch from the lens. Autofocus on this model works perfectly. I can examine unreachable objects from any distance. 5 MP lens gives great images. Works perfectly with my Windows laptop. Couldn't get the Google Play Teslong HD Camera app to work on my Note 9 but that was a permission issue. Couldn't grant camera permission to it no matter what I tried. Finally downloaded the apk from the site in the instruction manual and it works. USB C adapter gives a flimsy connection, probably will wrap it with tape if I use this with with my phone. This is a superior product for the price, if I ever need another I will definitely buy this brand. Note I did not try this as a borescope, no idea how useful this would be for pipe inspection but that's not what I bought it for. The cable is semi-rigid so it's much easier to maneuver in tight spaces. Yes, this is a real review. No one gave me anything or even asked me to write this review. Wayne Davis

You can't do anything with this useless 16 ft cable. It's flimsy and gets stuck in anything with even a 30-degree bend. Forget about using it near corrugated surfaces. The quality is alright, but the camera module (head) is huge and heavy, with a flimsy cable, which makes it a PITA to use. I returned it.

Pro: 1) Scope quality is impressive. It has a long wire which can be useful to reach inaccessible areas. 2) it has a range of light intensity which is easy to control and handy when light is dull or no access to light. It plays an important role when observing PCB boards with fine line trace width. 3) Software functionality is trouble-free and provides a wide range of options to change different parameters related to photo and video capturing/recording. Downloading would take no time at all. 4) Mobile-friendly application is super cool. Once you plug the device, the application automatically opens and starts showing live pictures. 5) MOST IMPORTANTLY, autofocus makes life easier than ever, you only need to hold device and it will automatically focus within 1-2 seconds. Cons; 1) You have to keep an object to some distance from the device lens in order to autofocus it. Device will not autofocus if the object taken to the range where it can not autofocus. 2) wire is little thick and heavy, because it is long, to make this device a desk gadget would include managing long wire and its weight. As I am using it to observe PCB and sometime with small array it becomes burdensome to make it still. otherwise the device is very good in quality and picture quality. I would recommended to all if you want to use it for purposes other than observing PCB with small traces that are smaller than human hairs.

Great product! the picture quality and auto focus stand out, compared with other two popular seller amongst the top 100 in Amazon. Good enough, but would be even better if the lights are brighter.

A quick delivery, needed to activate the OTG feature on my cell phone to get it to work, but after that it works great, found it has a good auto focus with a good depth of field.

Out of the few endoscope I bought, this one has highest image quality. The only downside is that the diameter is large (12.5mm).

I bought this about year ago and wanted to use this with my macbook air, but when i install smart endoscope app, it won't have option to add NTC125 anymore, only NTC200AF. How come product that is sold year ago have no support anymore? I would be very worried to buy this again if new needs to be bought every year or so, Also USB-C connection with adapter that comes with endoscope is very lose, disconnects all the time. UBC-C should be default and rest of old standards should be with adapters.
