These Medeli/Ringway/Dynatone and other "mystery pianos" are a difficult topic.
Many people here might not actually have any personal experience of them. I don't.
Still it's common to think and say that they are crap. Which they might be.
So, an easy solution is simply to stick with Yamaha/Roland/Kawai/Casio/whatever else is considered as an "established manufacturer" that has the "stamp of approval" from Piano World Forum members.
The list might also include e.g. Korg, Dexibell and Gewa.
Medeli is very quiet on any technical details on their products. Recently they have removed some older models from their own website and there's no more anything similar to the Fame. It could be one of the older models with a low 64 note polyphony and awful sounds. Problems could include audible sample looping and unnaturally short decay.
It's funny that it takes German music stores rebranding Medeli pianos to even "leak" the name of the hammer action inside. Medeli does sometimes mention if the model has their K8 action. Otherwise nothing. We know there's a K6 that Kurzweil also sometimes uses and a German music store has "leaked" that some models have a mysterious "HA-88 S500", unless it's a name they made up.
So, there isn't that much useful information around. There are very few sound samples on Medeli's site, a few more on the sites of German music stores (Thomann, Kirstein, Musicstore...), Gear4Music and some videos on YouTube.
The sounds and actions could be "good enough" for many and there are also positive reviews. It would be easy to say that those people are just ignorant.
But if your expectations are not too high then maybe you could live with a Medeli(?)
What it is in that model that interests you?
- The shape?
- The number of various sounds?
- The backing rhytms?
- The price?
There may be better options.
Since you are in Benelux and adventurous with "lesser" brands, you can have a look at https://digitalepiano.be/SGP600.php
It sounds like an older Clavinova. And the touch is...a mystery.
Some higher end Dynatones have several distinctively different piano sounds. But they are not quite at Yamaha/Kawai level.
