This HDMI microscope is exactly what I was looking for. I was having a hard time with my mico projects and soldering. Now I can see everything. The picture quality is great, easy to use and the price was within my range. I'm considering getting one for my son too!

I bought this microscope because I occasionally do micro welding to replace electronic components. The quality of the screen is very good and the magnifications are perfect. All components of the device are of good quality, assembly, assembly is easy. The only complaint is that it doesn't come with an AC adapter or batteries for the remote control. I had to get a power adapter from an old phone over 2AH. That's why I give 4 stars and not 5 stars.

Bought for PCB , small electronics hobby purposes
It looks nice
metal in places where cheaper ones have plastics
The higher end units in the range are out of reach but this is a good compromise
The picture is clear and bright

Had seen some reviews on YouTube. When unpacked, it looked a bit cheap. But functionally better than I thought. The amazing quality with the 12Mpix camera and lens isn't too bad either. The construction is simple and feels cheap, but in my first picture it doesn't compromise the functionality and quality of the image on the screen. Haven't gotten the videos and photos on the PC yet. It also works with a rechargeable/mobile battery bank so nice and versatile and a mobile setup is possible.
The magnification with a sharp image is so good in terms of resolution in combination with the lighting that, in addition to electronics, it is also suitable for biological and photomedical applications such as viewing and enlarging the skin. That surprised me a bit. The camera and lens can also be removed from the stand and can therefore be carried on the go. The image is more stable under a stand than in the hand, but solutions to this can also be devised with some Macguy pens.
Software is basic but the instructions in the manual are easy to follow.
The wiring was designed to be a bit awkward, but I understand the reason and functionality behind it. I think this could have been partially integrated with fewer cable hassles and vulnerable ports. But from a simplistic cheap architectural side I understand the logic.
I sometimes find the light too white. A warm white color would also have been nice to see true colors. The white light is sometimes overexposed. The light is strong, but it can be adjusted and the microscope ranking is dimmable.
I find all kinds of settings icons on the screen very annoying. It distracts from the picture. I haven't found a settings function to turn this off.
Points for improvement:
Actually pretty good for the price.

1. Mobile crafting with fewer cords
2. Warm light option for true-to-life images.
3. More megapixels. The more details are visible. The lens magnification is good but can optionally be a notch higher as a mountable accessory.
4. Software option to hide settings and clock and date from the screen.
5. Slightly more robust wheel. so I can make better micro adjustments with the focus/focus point of the lens. Things are going a little rough now. I believe this is due to the coarser plastic grooves. Perhaps a metal rail is a better option.
6. visible buttons on the screen. The function is plastic, so black on black, and therefore no contrast. If it was colored white, it was more visible. More contrast.
7.USB-C

To be honest, I wasn't expecting too much, but I was pleasantly surprised.
Use it for SMD soldering, and partly for watch mechanisms.
You can choose the height (and thus the image section or enlargement) steplessly, and always focus.
Ergo, it is no problem to depict small SMD components in huge sizes, and thus also to read their labeling. Or zoom out a bit and then solder.
The picture quality is also better than I expected. However, the image quality of the live image is much better than that of the photos that the device can take.

Great image quality and overall quality. Comes with additional lenses, slide kit and remote control. What else do I need to use? lol But I've spent hours looking at stuff with it and fixing a few little things. It's pretty easy to use, but the assembly instruction sheet skips a few key steps. The manual is pretty easy to follow and has links to video tutorials. So this is helpful. I definitely love it

Cracking scope for micro soldering, very well made, huge working distance between lens and base, cracking display. The service from K&F Concept is amazing. I had a little hiccup with the stand and in 3 days they had sent me a new stand and a £50 refund for my problems. That's what I call service. Overall I am very satisfied. I've used optical scopes in the past, but as I got older my eyes started to focus on different points, making using an optical scope a pain.

I use the microscope for detaching small circuit boards. Even SMD components can be easily displayed and soldered in or out.
It's a bit stupid that the microscope turns on immediately when plugged into a socket, even without using the switch, but then doesn't turn off anymore. If you forget to switch off, the battery can run out and all settings will be lost.

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 :)

A very well thought-out device in all functions. Very good to use for my numismatic work.
I would have wished that the operating instructions had also been available in German. So I had to translate the English text. All done, and can work well with the microscope.
