I hope this appropriate to post here (and I hope I don't seem like advertising). This is just a recommendation.

I live in Southern California, so we have a major problem dust... especially in electronics. I've also purchased many cans of compressed air and was less than satisfied as it basically just seemed money thrown out the window. This is safer for the environment. I was convinced by the good reviews on it... If this thread is considered advertising, you can delete this thread and I apologize.
