I be use this on a Toshiba laptop , and it work as soon as the bluetooth wizard configure the device . the problem be , once I shut off the keyboard , I have to go through it all again . however , window bluetooth manager show the device be connect , but the keyboard do not even transmit a signal . at this point , I have to remove the device from the list device , and re-install it . then it work , just as before . but , I drive a limo and will use it to allow my customer to browse the web for tv and music video . and , thus , I need two . one for they , and one for I up front , in case something happen and I have to fix a problem . so , with the dongle that be in the drawer , they both work fine , at the same time . the bluetooth dongle I have , get confuse or something . but , I can not figure out why neither of they will function , even though they be connect , accord to window . that be a bit of a hassle , have to re-install they , each time they be turn on . but , that be most likely a system problem w\/my laptop and not with the device . I have see comment that the sensitivity of the pad be not all that great , and I find it nearly equal to any mouse . a slight more effort , to get the cursor from one end of the screen to the other ... . if it be not for have to re-install everytime I turn the unit back on , I would have ZERO complaint ... ; - -rrb-
