Metropolitan ED500 DataVac 120 Volt Electric Duster, White

Pros: Made in USA.
Comes with a good assortment of attachments.
Long cord.
All metal design, except for the nozzles.
Removable foam filter on the bottom of the unit
Works great and defiantly worth the money!

Cons: These are minor cons but here goes.
As others have said it is loud but it more than makes up for that in money saved by not buying canned air.
The soda straw attachment does choke down the air flow quite a bit but still works well enough.
The foam filter does fill up very fast if you are cleaning very dirty machines so check it often.

Other Thoughts: We at our tech department (k12 school) uses this regularly to clean out our workstations\keyboards etc. It has performed perfectly through the many hours of use (or couple hundred workstations) during the two or three years we have owned it. One thing to note if you leave the big nozzles attached be careful not to let it fall or you will split them pretty easy.

The unit can get very warm if used for long periods of time, this can be amplified if the filter is stopped-up. (The motor in this unit is cooled by the air flowing through it).

Pros: Blows WAY more air than any can
Mine's 2 years old and going strong
Good for cleaning more than just computers

Cons: Gets pretty hot when run for more than a few minutes
Extremely loud

Other Thoughts: It's a vacuum cleaner motor in reverse, very powerful. It has a little trouble in the tightest places (canned air nozzles go down to about 1mm, this only goes down to about 1cm), but if you're blowing out fans or entire computers, this is what you need. Take the computer outdoors if you can, the amount of dust it gets out can be overwhelming.

Pros: The canister on this thing is solid metal construction and is made in the good ol' U.S. OF A. It has 500 watts of power with a nice long cord and plenty of attachments (6) for getting into the nooks and crannies. the little flexible hose is nice. You could get creative and blow up mattresses or kiddy pools or any of that type of stuff it has that much power.

Cons: Not one, except for the loudness which does sound like a vacuum cleaner. And which it is but you just use the exhaust.

Other Thoughts: It blows canned air away without even a comparison. This day and age it blows me away that this is made in USA. That's great.

Pros: Excellent item, does all it says. Kicks b#2@^% for blowing out cases out on field calls. No more stupid useless canned air.

This may not be for the typical home owner but if you work on PCs for a living this will pay for itself in short order.

It is kinda loud but thats what it takes to blow that kinda air...

Cons: Really none

Pros: - very very powerful
- comes with different endings for precise cleaning or just dusting
- light and portable
- super long cable

Cons: - none so far

Other Thoughts: This is extremely useful tool for any technician especially when you work on computers ... you know the dusty ones that users never opened to clean before ? yeah these ones this unit with it's super powerful engine will blow the dust to " dust " !

Pros: I have used compressed air for a decade. This thing is probably 4ish times more powerful. I found dust flying from places I didn't know I could get out. Even if this died in 6 months it will be well worth it.

Cons: Imagine a leaf blower right next to your head, it is that loud. You get lots of dust in the face as well.

Pros: Very powerful for the size. Filtered air. Solid feel to it. No need to hold at specific angles or use in small bursts.

Cons: Pretty loud, but that's to be expected since there's a lot of power in small form.

Other Thoughts: Used this dust out a computer with 3 years of dust and it great job. $60 worth of canned air wouldn't have done half the job this thing did.

Pros: it works , it blows

Cons: its so loud you can't do it at night , sounds like a vacume cause the motor is really loud but that diden't take no eggs off cause i'll clean my computer with this once a week or couple days.

Other Thoughts: this thing will blow you're hair back from a mile away thats awesome lol

Pros: Build quality, attachments, handle.

Cons: none

Other Thoughts: If dont have one...buy one period. Or you can continue to buy dust cleaners every other month.

Pros: Works great! Lots of air pressure and has no problem blowing dust out of electronic devices.

Very good for cleaning dust out of external exhaust GPUs fans, as well as other fans.

Cons: None...

Other Thoughts: This is a must have for anyone who wants to keep there electronics device dust free and free up air flow pathways...
