In case you do go for it(A2813), remember not to get it wet. This model apparently still has the 2 piece sapphire-mineral laminate. That is the only thing holding me back from picking it up,am considering the V2 ultimate instead. I'd rather spend a bit more and have peace of mind than spend a bit less and have the glass fog up on me and wonder how to get it replaced.
And I hear those crystals are a pain in the ass to replace, they're shoved in that tight.
