This is a very decent full size wireless keyboard and mouse combination set.
The keyboard is quite responsive, solid, and reasonably quiet. It has all of the keys that I need (and more). It is slightly curved for ergonomic purposes, but the curve is so slight that you don't even notice it an there is not learning curve. The keyboard has legs in the front and back which can be adjusted to provide a fairly broad range of angles.
There is a zoom button which works with most operating systems. A volume control rocker and mute button are prominently in the middle of the top row. There are user programmable hot keys. Some of the keys which are frequently used with 'Ctrl', such as A X F C V B, have their function subtly labeled on the front of the key.
The mouse is comfortable (maybe a little big for a small hand) and the laser makes it very precise. There is some intentional play in the scroll wheel which allows you to move it about 3/16's of an inch to the left or right depending on your preference. It seems to me that the scroll wheel has gotten progressively more stiff over time (maybe I eat too many sticky treats at my computer). The buttons and shape of the mouse are definitely designed for right hand use (I imagine that Microsoft must make a left hand equivalent).
The radio frequency reception of both the mouse and keyboard are very good. The operating range is 6 feet, but I am always within 2 or 3 feet. I have had no problem with dropped signals.
There are 2 AA batteries in the mouse and 2 in the keyboard. Battery life on the mouse is shorter, probably from powering the laser. The battery status indicator tells you which batteries are getting low. The connection via USB is easy, and the software provided on CD is unobtrusive.
Since I bought mine, I have noticed that the prices have come down and you can get the set for about $40 if you shoparound.
I am very happy with my Microsoft Wireless Laser Desktop 6000 v2.0 keyboard and mouse set.
