Well, a lot of people said that the stock drip tip was really loose as well. A lot of people were looking to get one of those flanged custom drip tips that come in through the bottom of the top piece. But thanks for the info, and it sounds like there is no such issue with the v2 at any rate.It's actually designed completely differently. On the v1, the glass DT fit into the main top cap, and an adapter was included for a standard 510 DT. The adapter is what was notoriously loose.
The v2 has a native 510 DT hole in the top cap. A heatsink adapter is included that accepts the glass DT. So it's native 510, adaptable to the glass tip. The v2's native 510 hole works great with every tip I've tried.
