Before this piano, I only owned a very old basic keyboard, and therefore the upgrade step was obviously huge for my personal case.
Not being a professional player and having only played a couple of times in a Acoustic Piano, I can still tell that the key feeling is impressively similar. You can also tell that the texture in the surface of the keys makes a lot of difference when playing with sweaty hands (which is my case).
Also the sound reproduction is quite realistic and the only thing I would criticize as a minor issue is that I would still expect a bit more power when the volume is at its maximum level for some pianos, but still, the sound volume is still more than enough for the player. On the other hand, the rock piano for example, plays with great intensity and I would not complain about the sound volume on that one.
Regarding sound fidelity, my impression is that the bass sounds are really good, but the extreme acute sounds are not able to keep up with the same throughput/quality. Still, the overall sound quality is excellent for such an entry level piano.
The piano is also really easy to to setup and to use. The Chordana APP is not only practical, but also very intiutive to use, but beware that you need to have a up to date android version, as the APP does not support older versions of it.
The original piano packaging was carefully done and the setup of the piano itself is relatively easy, although you may need a set of extra-hands to help, as the piano is quite heavy to move around.
The only unexpected "surprise" that I had was that, when testing the piano for the first time, one of the keys was playing much louder than the others, no matter how gentle you would play it. However, after some intensive usage of that specific key only, it actually came back to normal volume and it has been working fine ever since.
Overall I'm very pleased with the piano and I would totally recommend this piano and I would definitely buy it again.
