Reasons To Buy

  • It is very light and you can carry it around easily.
  • check-circle
    The carry handle is very good.
  • check-circle
    There's no flex at all and the build quality is good.

Reasons To Avoid

  • Not good lighting in LCD screen.
  • No pitch bend wheel.
  • The My Setup button is used to just save 1 set of registration, not more.
  • No color options for the keyboard. Only black available.
  • Can’t power through USB power bank.

I am very happy with my purchase of the Casio LK-S250. Its worth the money I spent.

Though the speaker's not the highest fidelity but it is definitely good sounding for a small room.

Not all 400 tones sound best but there are many usable tones as well.

I like the fact that 77 of the rhythms are really well programmed and there's a good transition between the intro, the ending, the variation and the feelings.

I am just amazed that at this price level we get five different caught detection modes. I also like that at this price we get the OneTouch setting.

The mic input is also very usable as it makes it a very flexible unit if we just want to sing along and entertain our family and friends in our home.

It's not going to be suitable for a very large venue but for playing around and singing and having fun in a little small group it is definitely unbeatable.
