Casio CT-S100, I have owned this since new, I wanted to learn how to play the piano, it was fantastic, connecting to my iPad and using the app called Simply Piano, using a USB Micro to USB C, it all syncs beautifully. Unfortunately I found i had no time for it. Its well looked after and includes instruction and music sheet stand that i never opened.
No battery included, it requires 6x AA batteries or it can also use mains adapter but that is not included and need to be bought seperately.
