Logitech make awesome keyboard and mouse . Logitech make a mouse -lrb- v220 -rrb- that last I 3 year and have great support service . good stuff . this mk550 combo be no exception . very ergonomic . the keyboard and mouse be both programmable . something to point out : 1 . the keypad have a wavy contour make for ergonomic purpose . some may not like it . personally , I do not mind it . 2 . the padding on keyboard provide the wrist a comfortable rest while typing . 3 . the mouse work great and all , BUT it be not glossy as I anticipate to be . the surface be somewhat rough and unfinished . my brother have the same model mouse -lrb- m510 -rrb- , but he be glossy . so I do not know if amazon or logitech cheap out or what , but that be my only complaint .
