Opinions on the Koh Hepa Jet blower

Has anyone used this filtered air blower, and what is your opinion? I just emailed Koh and was informed that they have a Hepa Jet II with a static filter but I can't find any details on their website nor did I get any response from them when I asked for more details.

From what I've read, it's just a gimmick to prey on people's paranoia... I'd never even heard of one until I received mine as a gift, but since I have it, I do use it, but I don't think it's any "safer" than any other blower necessarily.

This is an older post but I just did a blog and youtube video on this blower and other blowers. You can see it Here

I disagree with Randi. Its not a gimmick and I think it makes a lot of sense to push clean air and not dusty air into your camera.
