What's the concept behind the holes drilled in that way? I have a couple that I would try it on, easy to drillActually no. It's my cheapo Chi You bus atty. I took all my attys I don't really use like Patriot, Nimbus, Chi You and drilled them with those step holes with a 1/16th drill bit.
I want those attys also but might as well try copying the air holes in those I saw and see if they work. Got to be honest this thing chucks after those drill holes. Sound is crazy ripping the air. Straight lung hits and clouds like I've never been able to vape.![]()
