Not to repeat the same positive things that someone else mentioned above.. For its price, it is a great value for money and the capabilities it offers are unmatched at this price point. You would need to spend almost double the amount to get the same capabilities from other brands. A search with reviews on YouTube from professionals will convince you better about this.
The menu may have, as many say, a somewhat "old-fashioned" logic, but there is also a channel on YouTube where you will find detailed videos, in English, on how to operate and use its more complex functions.. (Creating rhythms, sounds, etc.).
As for the quality of the keys and their sensitivity, imagine that I mainly use it as a piano (the piano sounds are very good) comfortably..
If it had one more octave, it would definitely be a dream

A VERY good keyboard from Casio that can easily replace (to some extent) a more expensive Workstation (since it allows you to create your own sounds, rhythms, beats, etc.) and even a synthesizer (as it includes faithful sounds of well-known synths from previous decades). It's difficult to learn at first (unfortunately, it's not easy to find a step-by-step guide or video), but once you get used to it, you can do a lot with it. Its sound is simply AMAZING with its 30W speakers, while the new AiX Sound Engine even makes demanding stage piano sounds sound like they're coming from a real piano. Sturdy, stable, compact (without any creaking). 61 touch-sensitive keys (the sounds get louder as you press the keys with more force or velocity). Over 800 sounds and tones plus 235 rhythms. It has MIDI output and two pedal ports. It has a USB port which I used to update its firmware. It weighs about 7 kilograms and is very portable (you will need a carrying case).
