I get this for when my laptop -lrb- linux -rrb- be ` dock ' under the external monitor , so I have a external mouse and keyboard too , without use too much desktop space . as it use just 1 usb port -lrb- the nano receiver be a must -rrb- , it leave 2 other free for use . I like this fact , rather than a wire keyboard and mouse ... the look and feel be good , I like the island style keyboard , although the key be smaller than they could be -lrb- not a problem for I -rrb- , with larger space between they . mouse button and scroll wheel feel nice and work well . point to note -lrb- but not real problem for I -rrb- : - \* -rrb- the keyboard light -lrb- caps\/num ... -rrb- will not work without install the driver for this keyboard . I be not keen on have to install a driver just to get something as basic -lrb- and standard -rrb- as a keyboard to work fully - I can not do that on linux and would choose not to on Windows either . \* -rrb- the battery in the mouse would not stay in if the cover plate be miss . a small design detail , but it make you wonder - they can not design a functional battery compartment ? but overall , both keyboard and mouse certainly work well under Linux and for my require purpose . my linux : cento 6.2
