Keyboard simple, no frills but nice and well finished (for a keyboard lower range). Ergonomics is ideal (when one is adapted) and mouse suit me much better than my razer (Orochi Black Chrome, so for portable and too small for my hands). I have another Microsoft kit (Wireless Laser 7000) and even if the mouse is beautiful, I prefer the mouse this kit (yet much cheaper but more effective (BlueTrack) in Office. As for the Amazon.com service? never disappointed since I am a customer therefore no surprise ... more than fast delivery and quality product. In short, 100% satisfied
