the best thing since Windows 7 !! the Logitech wireless backlit keyboard be a snap to install in about 20 minute and have perform flawlessly . the key be comfortable and have a nice tactile feedback ; the backlighting -lrb- 3 brightness and ` off ' -rrb- dim when not be use and come on when you hand approach . when the ` battery condition ' indicator drop to 1 -lrb- of 3 -rrb- bar , just plug in the usb cord and keep on work . with no cord , I can sit back in my chair , put my foot up and browse away . I have use it from as far away as 10 foot . the keyboard , along with Logitech 's wireless mouse -lrb- also from Amazon.com -rrb- have clear my desk of all those extraneous wire , leave room for more important clutter !
