I answered as a nanny who just bought an electric piano for her children. Personally, I will trust Cavoli. After all, cavalli is a piano manufacturer with a long history, which gives me a more professional feeling, while Casio gives me a greater feeling that it is a brand that makes watches and computers. As a layman, the two brands of electric steel will also feel that Cavalyi feels better, and fingers can hold the keyboard and grasp it better.
