Query: nice upgrade from Microsoft wireless pro

I previously had the Microsoft Wireless Pro keyboard and mouse set. This setup worked fairly well, but there was some erratic behavior, especially with the mouse. It seemed like the signal was not always strong.The Logitech Cordless MX 3000 has been great. I have had it about 3 months and have had no problems at all. The desktop I have is a fairly glossy black, and the optical mice don't work very well, if at all on it. The laser mouse works perfectly without a mouse pad on this surface.The keyboard has a nice feel, works without delay, and is fairly compact in dimensions, which is great and does not add clutter to the desk. The multi-media buttons are a nice addition, but not vital.Overall: they keyboard and mouse have worked very well and I think are a good buy in comparison to the other options available.
