The back of the notebook is raised a bit, this improves the airflow and may improve the ergonomics a bit.
The Vizo Ninja II features a on/off button and a socket for the power cable. The power button is a nice feature as this allows you to easily switch between passive and active cooling. For instance, while browsing the web or doing office work you could turn off the fans as this will increase your battery life and result in a bit less noise.
The USB power cable features a pass-through connector so you won't loose an USB port:
The big aluminum plate helps to dissipate the heat from your notebook but the cooler also has some active cooling: two 70mm fans. According to the specifications they have a noise level of only 20dBA but their max airflow is only 13.72CFM which isn't much. It's a bit unfortunate that Vizo uses 70mm fans, I believe better cooling could be achieved if they used 80mm, 92mm or even 120mm fans.
The underside features a couple pieces of rubber so the cooler won't scratch your desk and I suppose these rubber pads will also help to prevent slipping. Vizo screwed fan guards on the two fans but these aren't too effective as objects can still easily get stuck between the fan blades.
