Bests & Worsts Reviews from Amazon

if you are wanting to give a proper cleaning to a PC's internals and power supply this just won't cut it. The air pressure is pretty good but its just not focused enough like canned air to get the kind of dust that builds up in a computer out. It will get the surface layer fine, but the dust that has been there longer will remain and you'll have to use a can of air to get it off, even with the attachments. The air coming out of this unit also get very hot very quickly and that just isn't what i'm looking for in a computer/electronics duster product at all. The unit is VERY loud, louder than our home vacuum cleaner. To add insult to injury, there are no returns aloud from the vendor that amazon stuck me with even though it didn't say anything about that on the purchase or checkout pages. Maybe i'll buy an air mattress just so i have something to use this for.
