Ok, I think I just figured out the vaporstar. Finally.
I got the VS about a week before the PD. Therefore, the VS was my first vape. When I got the PD, it was so much easier, I just switched over and forgot about the VS. . . . So now it's about a month later, and I've used the PD almost every day. I'm not a total noob anymore. This chat about the VS then spikes my interest and I try it again. Wow. Not nearly as difficult as it was for me before, and definitely clouds the bong a lot faster than the PD (I think because of the biger bowl). Anyway, this time around its actually a bit fun. Very much like the old smoking ritual. The VS won't ever be my daily driver - the PD is just too perfectly easy - but it is a nice complement to the PD.
