the keyboard sport slick design , unique functionality , and it be the most comfortable keyboard I have ever use -lrb- in 15 year of pc use -rrb- . it be a little buggy when use with a KVM though . it will take some get use to , but once you learn how to work with a ergonomic keyboard , you 'll have a hard time go back to a regular keypad . it be a must-have for my fellow carpel-tunnel survivor !
