I love this keyboard ! I be replace a older Adesso ergonomic keyboard -lrb- Bondi blue , circa 1998 -rrb- , that still work perfectly , but I want the extra media key , etc. . I really want a washable keyboard , but can not find one for the Mac . I try a pc keyboard that be washable , but the backwards key drive I nut . everything on this keyboard work perfectly . all the extra key work , the programable key work , it be pretty quiet as far as I be concerned -lrb- other review have complain about all of these thing -rrb- , but I find no problem . if it last half as long as my other Adesso I will be thrill ! the driver install with no problem . identify the keyboard with no problem . I have no complaint , it be great .
