Firstly, I really thank thomann and dhl for shipping this on the Christmas Eve, I placed the order on 18th december and received it on 24th.
The piano feels really good, the keyboard is light, yet expressive, and playing it feels satisfying. I have also tried a roland fp-10 in store, but I found that action really sluggish, not fun to play. The kawai es120 is really good.
I find that it is actually easier to make pieces sound better on it, than on my acoustic upright piano. It might be the onboard piano samples.
I also managed to pair it with my pc using it's USB midi and it works with fl studio out of the box, which is really nice.
I find that the speakers are pretty good, but you probably need to play with the eq settings and the piano samples. I will mainly play it using headphones. Also, the instruments on board are also quite interesting, I really like the church organ and the strings.
Overall, I am really happy with my purchase and would recommend this piano to any intermediate player that would like a fair priced digital piano, without any compromises.
