Well, I think nobody is interested in pre-story, how I watched reviews of plenty of pianos, visited local stores and played many pianos, and were collecting money at the same time.
The most important thing - I wasn't disappointed. The sound is clean, loud and so much realistic due to dynamics allocation. I can feel the resonance. The polyphony also does the work. The weight and the feel of the keys are amazing.
Also, it's so compact in my interior and looks shiny and cool. Well, the only small complaints are the plastic controls pad and unrealistic pedals (compared to the real piano), but it's fine for this price.
So don't waste your time, as I did)
