I just got my Protege in today... and am patiently watching the batteries charge (it's killing me). One thing I noticed (more of an inquiry, not a complaint) is that the 510 atomizers do not screw in flush with the adapter. There is a 1.5 - 2 mm gap. I'm assuming this was designed this way to ensure compatibility with different brands of 510 atomizers. Does anyone else out there with a Protege have the same thing?
