This is an updated review. When I ordered the 3.9mm endoscope I received a product with an 8mm diameter tip as shown in my first photo and left a 1 star review claiming that the product information was misleading were.

The seller contacted me and offered to send me a replacement, believing that someone on their side had shipped the wrong item. I have received the replacement and I am very pleased to say that the endoscope is indeed 3.9mm in diameter at the tip as described in the product information. My second photo shows that. Many thanks to the seller for the excellent customer service.

I haven't had much chance to use the endoscope, but after just looking through the menu and playing with it a bit, I think it's a pretty good device and has a lot of useful features. I like that you can add a timestamp to the photo itself. Most importantly, this is one of the few endoscopes available with a tip diameter of approximately 4mm. Almost all the others I've seen browsing are 8mm or larger.

Note that in the photo of the menu screen (third photo), I haven't removed the screen protector yet.

Had a damp spot on the vent - you can get a good look inside with the camera to see what's going on, see example photo. Tip: Use the brightness control so that the picture is not too dark and not overdriven.

So the device comes with a fully charged battery - switch it on and feel good. Everything works intuitively right from the start and flawlessly! Absolutely sharp pictures. Attached are the pictures of the turbocharger of my MINI R56 JCW N14, whereby the camera was pushed in through the lamba probe screw connection on the downpipe. Absolute purchase recommendation from my side. No frills, as you are used to today, but what you need and that very well.

For the price unbeatable!
This is the cheapest endoscope with a moving head.
picture quality good.
Screenshots and videos are stored on micro SD (included) as with digital cameras.
Brightness adjustable in four levels.

This inspection camera was ordered to inspect a sealing sheet in a house with timber frame construction as a homeowner accompanying a renovation. The image looks sharp on the display and the camera has a sufficient refresh rate for orientation. Noise is tolerable in low light, but almost imperceptible in full light. The side camera is only sharp in the close-up range, but it is still very helpful for roughly exploring cavities, because you can dive into a borehole and get an all-round view without having to turn the camera head around the corner. The line can be easily modeled and remains easily routed over a distance of approx. 1 meter. This has proved beneficial in getting the camera free again, if you want to look behind an edge at some distance with a bent end. The long line is also helpful to form a kind of crank outside the hole in order to be able to guide the camera better.
I can't see any reduction in image quality in the photos after I've scaled them down to 50% as a test. I therefore suspect that the usable resolution is well below the specified 1080P. I haven't tried the accessories like the magnet, but the protective ring for the accessory thread sometimes gets in the way when pulling the camera back. A clear purchase recommendation for occasional use.

This endoscope comes with a German-language instruction manual. The camera is attached to a 5 meter cable and faces forward. Various mirrors, magnets and brackets are also included for attachment.
This endoscope is super easy to use. The monitor is also located on the control panel. The results are displayed there immediately.
The slide on and off is located at the top of the right side wall. The camera is surrounded by 6 very small LEDs. These can be switched on and off or stored three times. to use. This is not included in the scope of delivery and must be purchased separately. On this memory card you can take pictures of what you see and store them there.
This endoscope has a rechargeable battery. This is charged with the supplied USB cable.
I particularly like the ease of use of this device. It's ready to use right out of the box and delivers good pictures too. The cable is a bit stiff though. You have to bend this in the desired direction.
The areas of application for an endoscope are very diverse. You can look into pipes, but you can also just look into animal passages to see what's going on there.
I am very satisfied with this endoscope. It absolutely serves its purpose and the price is justified.

I decided on this device because I often have to work in a dirty and oily environment during repairs and therefore don't want to use my cell phone for evaluation. The operation is very simple and self-explanatory, just switch it on and click through the menu. The device can also be easily operated with gloves. The auto focus works well and the brightness of the camera can be adjusted, so one hand can hold the camera and the other operates the display. Photos/videos can be made quickly and easily at any time at the push of a button. I am completely satisfied with the endoscope camera and can recommend it without reservation.

The product corresponds to the description and is also easy to handle.
I inserted it twice in a sewer pipe, the picture quality is good.

Had a burst sewer pipe at my own house.
With this endoscope camera I was able to localize it very well. I sent the pictures to the insurance company so that the craftsmen could fix everything quickly. This camera saved me a lot of trouble. Thanks.

I bought the camera to see the cavities (door sills) etc. on my Audi 100 Avant C4 built in 1991 and what can I say the pictures speak for themselves.
