A purely amateur instrument. Hit a couple of songs while drinking with friends or play for yourself. That's why it suits me. The keys are semi-weighted, I would not advise even students. The mechanics are not even close to real. It is better to play through external acoustics (there is a line output), I play through a computer and Additive Keys. Native sound - sadness, trouble. But what do you want from an ultra-budget tool? In general, if you are an amateur and are not going to play like Beethoven, then this instrument is for you. Good toy for the money. There is a sustain pedal included.
I decided to include some pictures to give a better idea of my experience.
