I use it for practice. Nice marketing, nice reviews. Heavy. I expected to be, no problem. The feel is somewhat better than my Studiologic 900SL I sold. It is working, and no connection or MIDI issues. It is heavy as action, but not as heavy as my old piano. The keys are not weighted individually, and there is a significant inconstance in weight along the keys, with huge differences of nearby keys. Craftmanship is cheapo, I've looked inside with a small endoscope, and the wood is not finished at all. Also in some months the keys started to show inequal differences in the spaces between each other.(controlled environment as temperature and hygro). I am not Keith Emerson..so no rough playing or anything like that. The most bothering is the keybed noise, which can wake up people sleeping in the next room. Basically is the same as Studiologic SL, maybe somewhat more, because the metal case amplifies it. The "ïvory touch" keys are not even close to ivory..they are slippery plastic. The black keys have some rough finish on them, which makes a weird touch and sound during the first month, after which it wears off, and becomes somewhat better, but inequal, because on the low and high keys, which are less used - remain for longer. I find the velocity options also limited. For this amount of money - all these flaws - makes it a bad investment. I use it, and did not sent it back - because I have to practice (in relative silence), and also out of respect for Thomann, who was always reliable and nice to me. Surely it is better than some entry level midi board - but the keybed noise is huge, and the craftmanship is also mediocre. So the conclusion is: if you want to have a a piano feel, you have to buy a piano. There is no MIDI board whatsoever to replace it neigher as feel, nor playability. My badly maintained 140 years old piano washes the floor with it in all aspects.
