I've been looking for something like this for a while and I really want to like this product, but the most I can give it is 3 stars.
It's not entirely clear from the pictures but this is essentially a wireless keyboard glued to a plastic case.
There is not integration between the 2 -- the RPi will need the wireless dongle from the keyboard and the keyboard draws power from 2 AAA batteries instead of from RPi headers directly. Similarly you have to pop a small cap and reach into the innards to turn the keyboard on or off as needed.
The keyboard itself is of average quality. They keys work ok with me but the touchpad is a bit wonky, sometimes too sensitive, sometimes not enough, making things like drag/drop hard to control. Tap-to-click is enabled by default and be advised that vanilla Raspbian doesn't provide an easy way to disable it.
Build quality is ok, ergonomics are so-so, the case bezel gets a bit in the way of the touchpad and makes it hard to figure out if you're clicking the mouse buttons or hitting the case itself.
The small fan I got was DOA and not preinstalled (instructions are to shove it into place, no mount to speak of) but I wasn't planning on using it anyway.
Allowing the keyboard to draw power from the RPi (it works on 3V, I supposed you could just provide connectors to stick to 3.3V pins on the Pi) and providing room to mount a USB batter pack inside the case would make this a much better product even with the keyboard/touchpad limitations I've described.
