I've been using the Casio CDP-S110 for a 8 months now, and overall it’s a solid budget-friendly digital piano.
The key action feels surprisingly great for the price – not too heavy, not too light. It’s compact and super easy to move around, which is a big plus if you don’t have a lot of space. You can even run it on batteries.
Also, it's the cheapest white color option from budget-friendly pianos.
The built-in speakers are okay, but if you're using headphones, the sound is much better and deeper. Also the polyphony (64 notes) is a bit limited for more complex pieces.
Still, for the price? Hard to beat. It’s a great way to start playing without spending a fortune. Btw, quality is great, looks and feels way better then it costs.
