The solution by the Griffin Elevator is for near optimal. My MacBook is nun15 cm increase and offers an optimal viewing angle on the display. The top edge of the display lid is now at about 40 cm height.
Since I use the Belkin Thundebolt Express Dock with an external keyboard and mouse, be no problems when it comes to operation result. I also find that the MacBook very rests securely on the arms and is still safe even when using the built-in keyboard. By rubberized carrying arms and the anger eighth plastic caps at the front end, sliding down is not possible.
In addition, the part looks really chic, as it combines perfectly with the look of MacBooks, and is not too expensive. I would rate the value for money it regards as appropriate.
Because of the look and feel (brushed aluminum), the stand height, stability and the price-performance ratio, I rate this product 5 out of 5 stars. A purchase worthwhile.
