Well if that doesn't convince you, nothing will.
Looking at your triathlon posts further up, they may not be amazing for an open water triathlon the level of vision they provide isn't that wide, also you have to kind of stick them to your face when dry (this is my method at least) and then pull the straps round. So if they get kicked off by someone else, they'd be a bugger to get back on. Fine for lengths in the pool, though.
You're actually not too late. I did buy the Zoggs Predator ones but they didn't fit at all so I returned them. Decided I should go and try some on instead, but never figured out where you can actually buy decent goggles in a physical shop any more.
If they've got the replaceable nose-bridge etc. then they might be alright for me. Might take a punt seeing as they're only £3.
Edit: enjoyed this guy's review: "I've got a narrow face and my eyes are quite close together, but my head is also quite bulbous and so quite big in circumference, considering how narrow it is."
