Casio CTK-520L

Keyboard 61 keys full size, 5 octaves so, hit toy kind, without any sensitivity. Unplayable for a pianist.
Headphone output.
9V DC power jack.
No effects section. No sequencer.
100 sounds divided into 10 categories (acoustic pianos, electric pianos ...), non-editable.
50 beats, divided into five categories (rock, pop, jazz, baroque ...).
40 pre-recorded songs; must-classical themes (Chopin, Mozart, Beethoven, Tchaikovsky), jazz standards (Oh, When The Saints, Misty), Ultra-known pop songs (Imagine. ..).

UTILIZATION

Simple to use! We choose a sound, a rhythm, a song and have fun ...
Same operation as the Casio CT-700 (see the reviews), in even simpler.
We can learn to play the songs in three steps, of increasing difficulty.
There is not really need the manual.
The only problem is that, that we take the sounds, rhythms, and songs, everything is terribly wrong! The sounds are awful, the repetitive rhythms, and accompaniments of songs in very bad taste (the techno-pop on Little Night Music, still ... have ...).

OVERALL OPINION

Purchased there over 10 years, the toy department of a department store.
Its advantage? Its very simple.
The disadvantages? The rest!
I'm using it more, and I do again this choice, obviously.
But we must not forget that it was a toy ... actually quite endearing, and indestructible (the "frame" is metal, plastic scratch proof, unbreakable ...). A strength which could be used by brands more "upscale" kind Kurzweil, whose products are - sometimes - poorly finished ...
It was a tank, I'm sure this toy still works despite years of neglect!
