I be really impress by this thing . almost to the point that I feel bad for the manufacturer . they put a lot of think into this product , and from what I can tell , hope to sell it for $ 80 or so . but it be probably just not in very high demand , so I feel like I get a great deal at $ 30 . so basically , it be just exactly what it say . you plug a tiny little usb dongle into a computer , turn on the remote keyboard and away you go . I kind of prefer use it compare to my new netbook keyboard . here 's why I say it be thoughtful design : 1 -rrb- the plug stow neatly inside the device when not in use -lrb- maybe you carry it around for presentation -rrb- . I be worry when I see one of the user submit picture , it look like the plug or a antenna stick out of the device . it do not . 2 -rrb- the keyboard have a backlight . very nice if you use it in the dark . 3 -rrb- you can -lrb- logically -rrb- turn the trackpad 90 degree . so you can hold the device vertically if you be just do mouse work . 4 -rrb- the supply usb charge cable do not consume a usb slot . how ? it split off a mini-usb plug from male-female usb cord . so the cord just extend the usb port of the computer , while also give a mini-usb charge point . 5 -rrb- it have a laser . I mean , why not ? it just really feel like they think this thing through . -lrb- the poorly translate chinese be hilarious though . fortunately , there be no real need for direction . -rrb- the only flaw be that it feel light in you hand , and that be a strange thing to complain about .
