Perfect for portable use and its price. My daughter is thrilled with it and takes it with her on vacation. The USB/MIDI input makes a big difference because it can be connected to a PC or tablet, and for example, in Simply Piano, it can synchronize with the notes you play to grade and improve you, without needing to "listen" from the speaker (which makes it unreliable).

I have been using it for about a year and it is not a child's toy. It is an incredibly portable and lightweight keyboard with an interesting and easy workflow. It is value for money because it can also be used as a MIDI controller with my choice of DAW. The keys, although small, do not take away from the joy of experimentation. The arpeggiator with its various patterns is easy to use and, combined with the metronome and recorder, can accompany me in a very entertaining way. The sound from the speaker is average, but with headphones, the experience changes. What I don't like is the uneven volume in the various samples. For example, piano samples may sound loud and clear, while some string and bass samples require hitting the keyboard to be heard. The keys have gradation in velocity sensitivity, which is very convenient when using drum kits. The drum kits are satisfactory but nothing exceptional. In addition to batteries, I can power it directly from a small capacity PowerBank for hours since its consumption is less than 500mA. I do not regret the money I spent in any case.

This particular keyboard has a manufacturing issue with the power supply. I purchased it on 28.12.2019. It stopped working because the USB port that provides power broke within a week, I repaired it and it broke again on the same day.
