Just got my Delrin Drip top today. popped out the end cap, and popped this in. I think I like it! Definitely easier to hold in my teeth... and, (don't call me crazy)... I swear I'm getting more vapor. Perhaps a psychological thing? (which by definition, would make me crazy, right?)
So far, liking it!
EDIT: Ok, confirmed, I am getting more vapor with the Drip tip. not sure why. I grabbed a new cart this afternoon, and didn't have anything to pop out the cap with. So had to use it without the Drip Tip for an hour or so. Was very aggravating, as I couldn't get my "hit". Soon as I got home, popped the Drip Tip into it, and voila... luxurious vapor! HAHA!
