This microscope gives a very good image quality for my repair work on old electronic circuit boards. The manual is of poor quality but fortunately there aren't that many features. Another minus point: the span is rather small, this is a problem with large boards where I can't reach the center of the board.

Anyone who is inexpensive and what makes a good impression (by my standards) is in the right place. It does what it should and the picture quality is also great. Of course, higher-quality devices can do more, but for private use it's a great thing.
It feels solid and I would buy it again and again.

The K&F Concept is a really good product with really small problems, but they can be solved easily and without extra charge. The 3D in the product name is of course wrong. The image is 2D and it takes a bit of practice before you can actually hit the components or the solder seen through the screen. It's still a screen and a camera.

The setup is easy. The wiring is a bit confusing and requires a couple of zip ties that are not included.

The first problem is the jack plug for the lighting. If you don't need the lamps, leave them and the lamps off, but most users will not want to do without the lamps. The protruding plug increases the space requirement on the workbench. Also, moving the microscope while using the plug to collect things on the table will constantly drag him left or right. Simple solution: loosen the two screws under the plate and turn the cover including the plug inwards. Be careful with the thin cables inside the box. They are very fine and should not be pinched. Once the screws are back in, nothing can happen and the connector is hidden under the base plate. I have no idea why it isn't installed in advance.

To enlarge the base you can also mount the arm the wrong way round. This is useful if you want to get mainboards under the camera. Especially here the above modification is useful, because the connector does not interfere. However, you should put some weight on the plate. You can now work on your silicone mat for this.

The height is an issue. If you bring the maximum distance between the circuit board and the lens, then you have to screw the camera to the lens ring. Not only does this sound bad, but it also provides a decent lever that will damage the camera if you move it clumsily. I used the 3D printer to print an extension with a mount that doesn't need any screws at all. The model can be found on relevant model sites under the user "Geit_de".

Once you have completed the assembly and eliminated the small problems, you have a device with which you can work wonderfully. I have already done some SMD work and this microscope is also ideal for checking something quickly or just being able to read the imprints on power supplies.

The cable remote control for the brightness is actually not needed and is probably due to the fact that two products (microscope and gooseneck lamp) were thrown together. The wireless IR remote control, on the other hand, does not make sense at first glance because you can do all the settings with the buttons on the display. However, as soon as you use the recording function or operate a large display or even a projector via the HDMI output, it looks more professional if you use the remote control, because every keystroke shakes the device and the resulting image shakes and the recordings or display are blurred.

Despite the small flaws described above, I am satisfied with the price-performance ratio. Of course you can build something like this yourself today with a little tinkering and components from China, but that takes time that you actually want to invest in repairs and other soldering work. Whether the result looks professional is another matter.

100% buy recommendation from me.

So the picture is great and I can zoom in super close from the sheer functionality the product more than meets my needs it's really fantastic. The only thing that bothers me are the buttons and the height control. They look very cheap and work flawlessly.

Works great with soldering. Plenty of space underneath for comfortable working.

love the picture quality. Just wish you could connect it directly to a PC to at least view files. It can be done with the included micro SD, but it's fiddly. Otherwise a great product and nice to have different lens options. Able to maintain a comfortable working height even with hot air tools in hand.

SOO beautiful

Outstanding image quality and functionality. I am very impressed.
Most of the device seems to be of good quality. Exceptional value for what you pay.
I like that it comes with an SD card and that the card slot is easy to remove and add cards. Other models from the same manufacturer have no indentation, making it almost impossible to remove/add a card without tools.
I wish there was a mount for the extra lenses. I'm sure I will lose or damage them.
It includes slides for some reason. I guess to test it? Seems like an unnecessary addition.
The infrared remote control is required for some functions.
The display is of very good quality. And the camera also offers excellent image quality. Such great value.
The assembly process made me think a few times. There are some limited instructions. But they don't match the Ikea quality I'm used to. It will require a little thought. I had to remove a plastic cover to slide on an assembly that isn't listed in the instructions but is required.
The clips are slightly further back on the small item plate. The camera can't go back that far. I can definitely recommend the high-quality K&F Concept 9-inch HDMI USB microscope 2000x and am happy to give it 5 stars.

Will be using this for soldering and coin viewing. The other lenses and also the output to PC and HDMI will be checked later! Can focus full coins in a really nice way. Very happy with it so far :)

Product arrived in great shape and was fast shipping. Communication was very good as far as shipping history. Would liked to have had user manual or instructions included. Do like the size of the screen; prefect for viewing coins.
