Product Description:
Designed to uplift, mStand is made of a single solid piece of aluminum that matches Apple's MacBook Pro's sandblasted and silver-anodized finish. Working on a laptop can strain the eyes, neck, back, and arms. Prolonged strain may lead to health problems or injury. mStand raises the screen to meet eyelevel for better posture and view. It also raises the screen to the same height as external displays, such as the Apple Cinema Display. The tilt design brings the screen closer and improves airflow around the laptop. The single-piece aluminum design provides solid stability and the aluminum panel cools laptop by serving as a heat sink. With an external keyboard and mouse, mStand transforms your laptop into a stable and stylish workstation that you can work comfortably and safely at every day.This product is designed for the following systems:Apple MacBook;Apple MacBook Pro;Apple Powerbook.

Rating : - Great design
Great and very sturdy design; has soft spots where the laptop makes contact so as to not scratch it. Soft spots are also underneath so it doesn't scratch the desktop either.
Note: it's meant to be used with an external keyboard and mouse; typing on the laptop placed on the stand will result in an uncomfortable (and non ergonomic, carpal-tunnel syndrome inducing) position. The stand "documentation" clearly indicates the use of the external keyboard.

I have a Macbook Pro (15.4") and it matches perfectly the design.
All in all highly recommended!
