This is the most useless product ever created. It is a fan, there is no vacuum power whatsoever. The turbo button made the fan spin faster. The air from the van comes out of the vents supposedly designed to keep the gadget from overheating. Absolutely no vacuum, and the air from the fan doesn't even come out of the attachments so it cannot clean anything. Your laptop will be just as dirty after buying this "vacuum" as it was before you bought it. The light on it does work, but only illuminates the dirt in the laptop that it cannot clean.
