Works very well!

Typing this using it on my PS3 right now

Keypad is very similar to my G1 keypad so I feel right at home with it.

Mouse is a nice touch if you want to use it standalone, but when attached to a controller it`s probably easier to just use the sticks.

Really can`t notice the weight when attached, so no balance issues.

When you want to type, you naturally tip the controller toward yourself so it`s actually quite well placed.

A worthy investment, makes in game messaging very convenient, no need to reach over for full size keyboard or mess with the standard text entry system.
