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. We have had the chance to review quite a few of their offerings so far and all of them have an excellent build quality and do perform well. The mini Ninja II does the job quite well, just like the other versions from Vizo. Nonetheless, while the unit does help with aging notebooks, new and modern portable devices do not require such an additional unit. For those still using that old notebook as a secondary computer stationed at home, the Vizo mini Ninja II can mean the difference between an always freezing or rebooting maschine or one that runs well and does not crash.
