The dust has settled and many companies have introduced notebook coolers. Vizo is one of the few that go for uncompromising build quality in addition to a unique design and additional features. The Ninja HS is a very elaborate notebook cooler made of heavy duty materials, which makes it almost indestructible. The little wheels on the bottom make moving it out of the way easy in case you suddenly need some extra desk space. The use of USB to power the two fans is a good choice, even though the unit cannot be considered portable. To make up for the lost USB 2.0 port, Vizo has also added a USB hub, so you even end up with one additional port instead. The Ninja HS is a great testament to the dedication Vizo has put into the entire line-up and nicely shows how the product family has evolved over time.
