I bought a CT-S1 a couple of days ago. The sound from the built-in speakers is excellent, especially given it runs on 6 AA batteries. A fantastic, portable piece of kit.

Very helpful, thank you. I made a PDF that I printed out on a sticky label sheet, which I sliced up and stuck onto the keyboard. You can download it at https://stevecaplin.com/wp-content/uploads/2021/07/Casio-CTS1-keys.pdf if you think you'd find it useful.
