I learned to play the piano on my parents old old upright piano. It's so old that the keys are really easy to press down.
All the electrical pianos from Yamaha and Roland try to mimic the feel of a "real" piano but they are all to stiff for my liking. They are all so hard that I can't play as fast as I want.
So I tried some synths. But they are all way to soft and plastic.
This is the perfect middle ground, not to soft but also not to stiff.
With these keys I can play soft piano music and synth solos.
All I really cared about was to keys, the rest of the midi board I haven't used yet.
But I can say that the overall piano feels a little cheaply made, the sliders and knobs and so on. So the quality is not as luxurious as you might think in this price range.
