Hey, I haven't experienced this (since I use the 2.0 coils mainly), but does your top fill close and lock? I ordered two and both of them broke right away. I think this is a defect, but I'm not hearing many people talk about this tank at all. I can't imagine that I'm unlucky enough to get 2 that happen to break in the same way. Basically, once I close it after filling- it just spins and spins open to shut. It doesn't righty-tighty shut and lock; if that makes sense.
Also, both of mine leak beyond words- pretty much the full tank. It could be related, if the vacuum seal isn't catching, but I just can't believe no one else is talking about this. Just curious if this is just me.
