Review for a Yamaha YPG-535 Keyboard?

Hello there, I am just wondering what are the features of the Yamaha YPG-535? Things I want to know are things such as does it come with touch response keys, like the lighter you hit them, the lighter the noise you will get. Also does it have weighted keys or not? If there is anything else you may think I need to know please do inform me. Thank you very much.
