The keyboard was there lodged within 2 days, two AA batteries and maintain as the Apple novices to say "It just works!".
Processing quite well. It conveys at first glance a high impression. On closer inspection, man detects very slight errors with respect to the gap dimensions.
But do not interfere.
The trackball is made of metal, it can be well and smoothly navigate this. The mouse and the keyboard keys have a pleasant pressure point. Thus, even long chats are not an issue on the sofa.
No termination of the connection to 3-4 meters (my living room is small :)
Runs definitely under Windows and Linux
(Mac certainly I have not tried)
For the money can be the keyboard recommend highly
