This thing is titanium sponge for concentrates. Keep your heat high and your tip aimed slightly upward while heating, concentrates can take more heat than flower. Things to look out for: Beware of large dabs, don't put your snapcap all the way on 'til you're used to it, and check your condenser tube for buildup every few loads. As for cleaning? Dynavap suggests soaking in nonflammable cleaner with occasional agitation, and I suggest listening to them - a cleaned-out concentrate pot is the perfect size for a dynacoil to fit in.
