this be a nice keyboard\/mouse combo , as long as you be okay with the fact that it do NOT have a built-in bluetooth system -lrb- that be , you have to use the little blue-tooth usb adapter and plug it into you machine for these to work -rrb- . I primarily use a mac with they slim bluetooth keyboard , so this be a nice analog to the Apple product . however , for whatever reason , this keyboard always start up with the number lock set to `` on '' in default mode , which make log into you computer via password tricky until you realize it be on and you turn it off . I do not know if this be a os quirk -lrb- I use it with a Windows 7 pc -rrb- or not , but it be a bit inconvenient . otherwise , the product be not bad for the price , and it be actually one of the very view product ad I see that disclose very clearly the fact that it work with the bluetooth usb adapter -lrb- other product try to `` hide '' this fact , which I find extremely annoying - we have to send one back that we purchase and do not realize it be all usb cord-connected and not bluetooth adapt or internal ! -rrb- .
