I get this so I would not have to use the lame arrow key to type on my TiVo Premiere . this doe not come with a usb dongle . I buy a cheap one from best buy , plug it in and I be initially disappoint . it be not really responsive and have a range of about three foot . then I use a usb extension cable to move the dongle out from behind the TiVo . that do the trick . it work perfectly and make typing on my TiVo really easy .
