Background
A portable electronic keyboard with 76 piano-style keys and an LCD screen. The keyboard has a black control panel with white speaker covers and a grey body. The model number is etched into the underside.
This keyboard was released in 2011 as a replacement to Casio's old CTK-4000 model. The differences between these models are mainly cosmetic, except the WK-220 has 30 more built-in tones than the CTK-4000.
The keyboard is light enough to carry around, has had no major recalls, and has mostly positive reviews. Newer models haven't advanced much and don't include many additional features, so we recommend repairing instead of buying new.
Identification
This device can be identified by model number WK-220.
