Got this to do routine maintenance on my MacBook. It's pretty much common knowledge that you don't turn these upside-down, but apparently if you hold it at a slight angle, it can also spray the super-cold propellant out. Trust me by the permanent discoloration on my forearm, you DON'T want to do this. In the end, it did it's job.

I've used my Dynex Duster twice since Christmas and both times it provided a good strong blast of air that blew a surprising amount to dust out of my keyboard. It also did a remarkable job on my printer. Now I suppose other such devices might work as well, but I can't say that yet.This is the only one I've tried. How long it lasts will be my primary comparison with other compressed gas dispensers. So far it has done the job that I expected.

It's always a strange thing to pay for air, and I must say these air cans are a bit overpriced. But if you have a laptop that you use often, then you probably know all too well the extra heat it starts to produce when the fan gets clogged with dust and fuzzy stuff. I air my fan and vents out once a month to keep the cooling system working well.
