I've been using mine since before the begining of the summer of 2007 and they have never fogged on me since. They have great comfert and stability but a little hard to get a bounce off the face peice. I havnt gotten shot in the face yet but i have taken spray on it and it is a very easy mask to maintain. The straps worn down a little fast on mine because i keep them as tight as i can on my head but that isnt a problem. I like the look of the mask because its got that hey im not a renter so i wouldnt try bunkering me look (lol :) ). I must say though even though my lenses can a little bit scratched they are so good that every time i put them on i see a scratch then realize they are my eyes reflecting.
I highly recomend these goggles to any one that needs a new pair because they are cheap, rekiable and easy to maintain. At around $35-50 (depending where you are from) you cant go wrong.
