I've noticed lately that my Sphera is leaking, as well, but mine isn't even that old; I got it in June! It's probably just the shape of my face, I always have a heck of a time finding masks that fit right. I was having so many problems with my Sphera leaking during my PF course that even Paul and Kirk inspected it to make sure the lenses were ok. It seals to my face perfectly (even with a slight vacuum holding) as long as my mouth is closed, but as soon as there's a snorkel in my mouth, changing the shape of my face, the vacumm releases and...glug glug glug. I can't even have more than a day's worth of facial hair, since mine is SO stiff that I suspect it pushes the skirt away from my upper lip enough to allow leakage; kinda like trying to get the mask to seal on sandpaper. I've been shopping around for another new mask, but I'm not sure what to look into.
