I checked this out a while back. Looks good but has received bad reviews here and indifferent reviews here. The chief complaints are noise (which I can deal with) and low air pressure (which I wouldn't be able to deal with). One review at Amazon pointed out that the directions cautions against leaving it plugged into the charger too long; I would find having to deal with that unacceptable.
There is an industrial model available at Amazon. The reviews are a bit better but the price tag is huge.
I've been eyeing this unit for a while (don't let the word Vac in the name fool you; it is a blower, not a vacuum). It looks far more promising than the O2 Hurricane despite the long umbilical (aka power) cord (one reviewer said 15'). It's less expensive and far more powerful (see the second video in the reviews; the guy was actually blowing a computer mouse around!). I still have three full cans of canned "air" knocking about the house so I have some time to decide if I can deal with an umbilical cord in the way. Also, I need to figure out where to put it (a can of gas can be kept out of the way in a drawer but this would have to be kept out somewhere already plugged in to be as convenient).
