I've bought the keyboard and am ebenfals very satisfied.
Before I start my praise I want to mention briefly that there is an "American keyboard". In other words, "Z" and "Y" are swapped, and there are no umlauts as "Ä" for example.
The keyboard is excellent write despite the small size. Of course, one must note the size! Only the rear keyboards (blue and orange) are a bit fiddly to use. But, hey, that's really no wonder. The buttons can strike each other perfectly.
Continuing with the touchpad. At first I thought "Huh? That's all not at all!", Then I took the instructions on your chest and then everything was great. So read instructions bringts but actually. I come with the touchpad cope wonderful and it is fun as the Playstation to "surf" or to scroll through the menus. A real keyboard and a real mouse, of course, still better, but the comfort is not there at the Playstation halt. A great solution!
The keyboard can easily be clipped to the controller and take off again. It bothers me the keyboard when not playing at all. Super heavy it is not. Attached to the Contrller the keyboard looks really smart and forms a unity with him.
A great product.
