I type a lot for my work, so it was a surprise that my Microsoft Sculpt keyboard and mouse started wearing-off sooner than I expected. The Logitech MK545 combo felt like a good simple replacement. Its keyboard has a good layout, with just the right keys and not crowded than what's necessary. It has standard function keys, a calculator key, Windows lock key (handy), media buttons, and volume keys (takes a few presses to work at times). Typing is soft and comfortable. Keyboard build quality is decent, but it can be better at this price point. Hand-rest should've been a little longer for full placement. The mouse is just the right size for my hand, not too small and not too big. But Logitech should make the mouse clicks a bit softer. Overall a good combo for everyday use in home or office.
