So i caved and got another quartz insert to try from RubyPearlCo figured for $20 who cares. Its a fitted opaque insert. Produces decent vapor on red probably comparable to the ceramic insert on green. Have taken a few dabs so far and there is zero chazzing. Gonna keep messing around with it. Def an improvement over the fadespace and eq inserts i tried last year (before eq was making fitted and opaque inserts)
