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. It can be switched to German and everything that can be set where is understandable. The device can also be easily operated with gloves. The autofocus works well and the brightness of the two cameras can be continuously adjusted using the wheel at the top right, so one hand can guide the camera and the other can operate the display. Photos/videos can be made quickly and easily at any time at the push of a button. Switching between front and side camera or both can also be selected at the direct push of a button, also the mirroring to turn the writing the right way round. Accessories such as magnet, memory card and USB cable are included. The battery was half full after delivery so the device could be tested immediately after delivery. I am completely satisfied with the endoscope camera and can recommend it without reservation.

During the last heavy rains, water ran into our basement. I then suspected a rainwater downpipe that runs inside a house wall and weighed it up: buy it or have someone come directly with equipment? In the latter case, 200€ are quickly gone with the journey, as I had to find out myself.
I then decided on this device with a dual camera, which, as you can see from the example image, was the right decision. Of course, you can't control exactly where the camera head is, which is precisely why the dual camera is helpful, because by rotating the cable you get something more in focus with the side camera than with the front camera.
You should actually always activate the video recording immediately, because in case of doubt you can record places in between that you can no longer reach / focus on afterwards. The videos are saved uncompressed, which is not a problem at first since the memory card is large enough. If you want to send the videos, you should then compress them afterwards with common tools.
Sure, it's not a professional device and the image quality on a large screen is only moderate. But you can't expect more in this price range. But it is enough, for example, in the event of a pipe burst, to get an initial picture of the problem and then to see where the problem lies and whether the professional has to come or not.
Of course, I can't say anything about durability yet. Anyone who has to use something like this on a daily basis is more likely to buy a device in the middle three-digit range.
All in all I am very satisfied and give a clear purchase recommendation!

This is great to have around, it’s very handy to check drains or small spaces in a house.

Must check gutter. Insulation pipe and bend taken by the electrician.
Camera plugged through. The camera looked out about 3 cm at the front of the pipe bend.
Skylight opened and camera with tube pushed over the roof to the gutter.
No kinking of the 5m long camera line. No fumbling around when pushing over.
perfect picture. Pipe rotated 180 degrees with camera and checked the other side of the gutter.
Everything perfect.

Love it, good quality pictures for price of device was able to find coolant build up and use photo for warranty work

Very happy with the quality AND the price.

It is as easy as turning it on . I used it to locate and extract a rock from inside my spark plug cylinder.

My husband is a mechanic and this is so small it gets in those tight places he said. It is a good item to get and great deal for the price.

It does well in small, dark spaces and has a great quality picture

Good picture, small scope easy to manipulate.
