Bests & Worsts Reviews from Amazon

I was trying to decide between the Metro Vac ED-500 duster or this all-in-one duster / vacuum. I really wanted something that did both so I decided to give the DataVac Pro a try. I saw some great reviews, and some not-so-great reviews so I was a little worried. I have to say, I love this product! The vacuum part is what you would expect, and does as good of a job as a regular upright vacuum with a hose. The vacuum comes with a hose, regular sized brush, crevice tool, pinpoint cleaner, and a micro cleaning kit consisting of a micro bursh, crevice tool, and flexible (somewhat) straw attachment. Everything seems to be of good quality and is made in the U.S.A. the canister is metal and the vacuum comes with 5 extra bags + the one already installed. There is no set-up out of the box, just plug it in and go. This product seems to be geared towards people in the computer or electronics repair field. As a computer technician here are my thoughts: First , the kind of dust you find in a computer cannot be easily vacuumed up by any vacuum cleaner (except for dust bunnies). the dust is so fine and almost seems electro-statically charged to the surfaces. That said, I like to vacuum up as much as I can before I blow the rest out. the blower works by attaching the hose to the opposite end of the vacuum. I would say the blower is probably more powerful than a can of air but maybe not as powerful as the ED-500 although I don't know for sure because I've never tried the ED-500. What I can say is that the blower is *MORE* than powerful enough to get the job done. I saw some impressive videos with the ED-500 blowing literally "clouds" of dust from computers. This blower does the same. I blew out a computer I thought was pretty clean and I got the same "clouds" of dust out of it (don't do this indoors) One thing I wanted to mention: I see a lot of videos where people blow out power supplies CPU fans, etc. In these videos you can always hear the fan spinning as air is blown at it. Yes, it sounds really cool, but this is very bad for the fan. What happens is the air is strong enough to over-rev the bearings in the fan and it will lead to premature failure of the fan or even immediate failure (i.e. your fan will start making strange noises right after you are done cleaning it) The proper way to clean a cpu fan, power supply fan, or anything else with a fan is to stick a plastic zip-tie, straw, or any other straight piece of plastic in the blades to block them from spinning while you blow the fan clean. Just don't forget to remove the zip-tie when you are done and don't use any metal objects, especially in the power supply. Even with the computer unplugged there are still dangerous voltages in power supplies.
