i tried to use the customer service button on the website, but it just kept kicking me back to the homepage. anyway. i placed an order 7/15, got it today (my parents had the mail held while they were on vacation. ah, the joys of living at home >.<) and the connector on my 510 passthrough isn't sealed.. there's a hole in the middle, and if i draw on it without an atty on there (so my lips are completely covering the air-flow notches on the sides) i still get a tiny bit of air.
