P-515 B : Value for money

Generally, it's good.

I'm using it to teach my students (kids and adults).

Pros. It's a good solid instrument with some rhythm. I would recommend it for students or home use.

Cons.

Maybe it's just me, but I found that the sound of the piano is weak and not as deep as other Yamaha's pianos. It can be reached by using dual-mode blending with another tone of the piano and adding reverb to it.

The fact of having wooden keys more irritates than makes it better. Kids are complaining that the corners of the keys are too sharp, it hurts their fingers. Though for adults it's not a problem at all.

Would be nice if USB could have common functionality of recharging devices as well.
