Ok --I just tried it on again and remember what my problem was...........for some reason I just CANNOT tell if I'm leaking towards the top of my nose because of all the darned air spewing out of those air holes!! I can tell somewhat by sound, but tell me, guys - when you get a good seal, is it quiet or can you still hear all that air gushing out?? I tried doing the back strap first, nothing too tight - seemed like I was still gushing. As Roger says "I really want to like this mask!!" And I do!! I just don't know if it's meant to be.
