No more burnt flavor, coils last longer, flavor big improvement, mor vapor, use it at a higher voltage/wattage.

Will use more juice but its well worth the improvement.

Don't like put the bushing back in.

I'm
vaping on vamo at 8+ watts when I want to.

* Higher voltage/wattage will burn more juice.
