88 keys, the account is good.
Below is not a keyboard is a toy.
We can add three effects, brightness, reverb and chorus.
Indeed when you test the piano, be careful that people who have gone before you have any adjustment. Just put a gloss 4 0 and a chorus for a while its really rotten.
is a USB port (very useful).

UTILIZATION

The touch is satisfactory.
Or even heavier than some pianos.
The plastic feel is acceptable and slipped proper.
It can be used to study piano.

SOUNDS

As for sounds, I'm disappointed.
I should have brought my headphone to the store.
This is especially the media who fish. They sound muffled.
Moreover, in these mediums, it is very difficult to bring out a FF a F compared to other keyboards.
Y as the sound generator that attempts to simulate the beating, but a villain.

OVERALL OPINION

Attention to weight, it does not look like that at the store, but it still weighs 47 kg.
In conclusion, it is a good keyboard for the price I paid (800 €).
Sound means, but low grades mediums quite realistic touch.
At this price, must make concessions, all keyboards have flaws.
I do not regret my choice even if I sound harsh, I'll spare you the comments that I could let other "keyboard" in the same price.
