And reminds me WAY too much of a glans... Sorry, couldn't resist.
As has been stated, the igo-w is a nice little dual coil dripper. I've been running one atop my magneto tube
mod for a while now and my only issue (again, as has been stated) is the height of the air holes. Mine came drilled out with two, which I widened to 1/16, but they sit
just above the drip well and will leak from time to time.
If Rob does decide to offer these as well, I'm pretty sure you can purchase them at a few places with undrilled top caps. Can't remember where I saw these, but they're out there.
