I was hesitant to purchase from this site because I wasn’t sure if it was legit or not, but it turned out to be the best decision I made. The same product on Aliexpress is higher price. The seller is very responsive, helpful, and all the provided instructions are enough to set up product. It is very easy, even for a beginner like me. This company is great and it is very obvious that quality is very important to them. They do things like include additional screws to secure the screen, so that it doesn’t wobble. I am willing to bet that the other alternatives on the market don’t do these quality of life features. Anyways, 10 out of 10. Great product, great company, and I will be sure to check them if I ever need multimedia upgrades for my other cars.

The product and the attendance
Only, in one word…
WONDERFULL!!!

I bought the 10.25" version for my 2016 GLC. I went with the smaller display as I felt the 12.3" version might be a little too large, and I'm happy with my decision.
Installation was fairly straightforward. I used a 'fish-wire' to route the cables behind the dash up to the Linux screen after removing the centre console and radio.
Build quality is good, and the screen fits well. I updated the boot logo to a Mercedes star using a .png file on a USB stick.
I've used the screen now for about 3 weeks, so have a good feel for its pros and cons.
Pro:
The device boots quickly - just a few seconds - this is the main benefit of the Linux screens over the Android ones. It means that if I need to see my reverse camera it is available quickly when driving away.
The screen is sharp, and the touch screen is responsive enough (not quite on par with a modern phone, but still OK).
All the functions work OK. I'm using wireless Android Auto, and this worked just as expected.
Air conditioning changes (e.g. when you change temperature) pop up on the display (although see my note about this below).
My OEM reverse camera pops up when I engage reverse, and can also be summoned by the camera button on the dash.
Connectivity has been good - Android Auto connects quickly & stays connected.

Cons:
The display isn't very bright - even with the brightness set to 100%. It's also quite reflective, so because of these two factors, it can be difficult to see in bright sunlight. I would happily have paid more for a higher spec (brighter/anti-reflective) display. If a 'pro' model became available in the future, I would buy in a heartbeat.
If the air conditioning is set to AUTO mode, every change of fan speed or air distribution that the car makes gets shown with a pop-up. This can be annoying if it is happening frequently, although I have found once the car is up to temperature it settles down. I did ask the seller if there was a way around this, i.e. just showing temperature changes if in AUTO mode, but he said this was not possible.

Overall though, I'm pleased I bought it - the screen has really brought a new lease of life to my GLC, however I will keep an eye open in case a new version with a better display is released in the future.

I was tired of paying software license fees to MB in Germany and was looking for an alternative solution, which I found with the 12.3” screen powered by a LinuxOS. It was easy to install for me (2hours) and the results are excellent. Fits well, new supporters without any additional adjustments. Software runs smoothly, easy to set up and easy on the fly personalized start up screen settings.

Fast delivery and excellent support.
Highly recommended
