Got this to find a wiring problem in our house. Rigidity of the cable was up to the task of pushing it through insulation in the wall. Camera image was great, plenty bright and large enough. Wouldn’t mind a shorter focus point but it is as advertised which worked for our needs thus far. Also used it to find a clog in a drain and used the magnet to remove a piece of metal that was causing the problem.
This one will get the job done!

Good picture quality and does the job

I'd previously bought an endoscope that used wifi to connect to my phone screen using a custom app from the manufacturer, but found that they hadn't updated the app to layer versions of Android, so it's now unusable.

This device has its own screen, so no such concerns. The picture was better than I was expecting, and I was able to submerge the camera in a water tank to discover why a pump was no longer working. This saved me a callout fee for a plumber to come and diagnose the problem, so it has already paid for itself.

It feels like the right sort of price point to pay for a tool that I will only use occasionally. There are some extra little gadgets that clip on to the end of the camera e.g. a hook, a small magnet and a mirror.

There is no pouch to contain the items, but I will just keep it in the box that it came in - it all packs away neatly enough.

Great product can be fit to glow plug and injector holes.

I was quite surprised at the image quality of this device at optimum focal distances, which is aided by a big screen (compared to most others).
I did look at the traditional design offerings (the ‘pistol grip’ type) as a couple of friends have them, but the resolution, illumination and a screen about a third of the size of this unit’s screen didn’t leave me particularly impressed.
There’s little point in describing the unit and it’s functions are these are adequately (and accurately) described in the sellers information.
In use, this does need some practice in terms of ‘wiggling and turning’ the probe, both to get it to where you want it, and to interpret what you are seeing which may at that point be ‘rotated’ from the ‘horizontal’ you have in your head. Once mastered, it can return an astonishingly detailed picture at optimal focal length (I’d say about 2 - 4 cm). Outside of that distance (as a pre-focused camera, it will actually see as far as you want it to), the image is less crisp, but still good.
I bought this to try to track down the cause of water leaking into the boot of my car which was leaving wet carpets. I was able to feed the probe up a box section in the boot area while leaving a hose running down the car’s roof. I was able to see where the water was coming in (very satisfying), which saved me any amount of stripping -out and trim removal. It was worth its price for this alone, although I couldn’t help reflecting on many, previous situations in house and car where I wish I’d had this at my disposal. Similarly, I’m anticipating this being very useful for similar situations in the future, especially as I’m not as young as I once was and tight ‘contortionist’ spots are getting more difficult as time goes by.
The last thing to comment about is the price. Some of the ‘professional’ units like this can cost three/four/five (or more) times the cost of this one. They might be more rugged for industrial use, but for DIY use this is perfectly OK.
All-in-all I’m very pleased (and impressed) with this device.

Works very well.
Good picture.
Instant response to movement. (no wifi lag)
Screen is good, and pictures can be saved to the card for transfer.

I'm a bit surprised. The device is really good. With the large selection, it was difficult for me to choose a device at all. I'm glad it turned out to be this one. The image quality of the cameras is good and was immediately convincing. So far I've only used it for sewage pipes, where the illumination is particularly important. The brightness of the LEDs can be adjusted using a stepless controller on the side. In this way, the illumination can always be adapted to the respective situation. If the camera is too close to an object, the image fades. This effect can then be compensated for using the slider. Orientation is no longer that difficult with the side camera. I can only recommend the unit.

Has worked flawlessly. After a cleaning with a motorized spiral was completed, I was able to use the endoscope camera to check that the blockage was completely removed. The two cameras in connection with the LED display and the split display for the front and side camera made this clear, so that in a few minutes it was clear that the blockage at a distance of about three meters had been cleared.

Really very good product, it does exactly what it should and everything has been thought of, 2 cameras for orientation on the front and a side camera. Both work from a distance of approx. 2cm - 3 meters to the object, the focus and brightness adjustment also work good to very good. Since you never know how the sensor is positioned in relation to the object, you can rotate the image by 180 degrees and even !!mirror!!

I have used this endoscope camera both in the hard-to-reach engine compartment of my vehicle and to inspect our sewer line and I find the image quality satisfactory in view of the fairly reasonable price.
If the clog in the drain pipe can be located (and cleared) without hiring a costly plumber, it's already a worthwhile investment.
Only the recording and storage function did not work and it turned out that the memory card was defective.
The seller responded obligingly and generously replaced the purchase price with a higher-quality memory card.
The durability of the camera will have to be seen, but will hardly be used due to a lack of demand.

In any case, the neighbors were already delighted that they could fall back on my "endoscope camera service" in an emergency. :-)
