This very light and compact endoscope camera comes in a hard case with a foam interior. The cable of the camera is about 5 meters long and has a diameter of 0.5 cm. Contrary to what is stated in the description, the camera is not equipped with 6 LEDs, but with 8. 6 LEDs light up on the front of the middle camera. 2 lights on the sides, each on the right and left. Cameras are also installed here. So you can look down (into the combustion chamber of the cylinder, for example) or switch on the camera on the right or left to look at the walls without having to turn the camera. Very good. The camera has a resolution of 1080p, i.e. Full HD, the recordings are stored on the 32 GB memory card supplied and can be called up at any time. The 4.3 inch display is equipped with hardened glass and is easy to read. The menu is tidy and logically structured. The language, resolution of the recordings, etc. can be set here. There are other LEDs on the side of the device that can also be turned on to act as a flashlight. The integrated 2600 mAh battery is charged via USB-C charging cable. A good choice for hobbyists and mechanics.

ordered the Teslong endoscope camera for examining hard-to-reach places. Since I will probably only use it a few times a year, it is perfectly adequate. You can't just compare them to a professional device. It comes in a handy storage case with foam inserts. Operation is clear, self-explanatory and the display is easy to read. The first thing I checked was the drain in the bathroom sink, because hair often gets tangled up in it and clogs it. I have to disassemble and clean the siphon regularly. Now I can inspect the drain with this camera and use the hook to remove any hairballs before they become a problem. After a bit of experimenting with the LED lighting, I got quite good and sharp images, on which you can also see details. The brightness can be adjusted in 6 levels and is completely sufficient. The recordings are stored on a supplied 32GB SD card and can therefore also be viewed later on the PC. The flexibility of the probe hose is pleasant and not too rigid. However, it is difficult to steer, so that it sometimes takes a few tries before you hit the desired position. It can take a while, especially over long distances. The additional lenses are very helpful because you don't have to work with a deflection mirror, as is the case with some competing products. I have no complaints about the processing. There are no sharp edges or burrs.

Impressed with the build quality. Works with a nice clear picture and comes with a nice hard shell case.

Overall is a great bag, it should came with wheels!

The tripod looks very stable. All the levers, wheels etc. seem to be solidly built and I'm not worried about my camera on the tripod. This tripod should last many years and serve me well for many photos.

You can tell right away when unpacking that this filter is of very high quality, because it comes in high-quality hard cardboard packaging. A very stylish and practical case is also included. The filter itself also looks super high-quality, scratch-resistant and works wonderfully!
You can easily screw it onto the lens and rotate it, although it's a bit stiff. But it doesn't slip either!
The price is quite high, but if you are willing to pay that much, you will have an absolute top product!
