the mk710 keyboard and mouse be at least my 10th set of input device , and up to this point they be the best I have ever own . the soft tactile keyboard have a feel that you would only expect from very high quality equipment , the mouse be just as impressive , and both piece be beautifuly design . yet the price be a downright bargain . the keyboard be also feature packed and very comfortable to use for several hour at a time . Logitech really hit a homerun with this affordable duo !
