For such money, the functionality of the toy and the workmanship are very good. But there is one problem that makes a musical toy unsuitable for proper music. All sounds are overloaded, and not at the output (the amplifier is very loud), but at the input. That is, even at the minimum volume, you can hear a characteristic distortion, almost a guitar overdrive, on all sounds. This leads to both unpleasantly distorted sounding of individual notes, and to mess even in the simplest chords - it's like playing a guitar with overdrive with full chords. For a person with a soldering iron, the problem is solvable, inside there are two separate boards for the synthesizer and amplifier itself, and the level can be lowered to achieve adequate sound, but, obviously, this is not suitable for everyone, but there are toys on the market that do not require such improvements.
