Works great!
I was so excited to find a Casio keyboard at a garage sale, but it had no adapter. I found this AC adapter on Amazon and Voila! It works perfectly. I’ve cleaned it up to sparkling and it is going to make a wonderful Christmas present.

It works!
It perfectly replaces the original Casio power supply. Only time will tell how long it will last. The blue indicator light is convenient.
