I like that it blows out the dust and dirt from my keyboard and wherever else I can think of dusting/cleaning. BUT, it will stop blowing out air after a little bit and you have to wait for it to "recharge" i don't know why. It is a nifty little thing though, I like it.

The officemax air duster keeps my computer keyboard looking new. I use it twice weekly to avoid a dirty keyboard for when my grandkids play on it
