One of the frustrating things about ecig studies is that they always use the worst quality hardware and puff really hard on them. The "Epuffer" looks like one of those "cig-a-like" which are notoriously worse than the much more expensive hobbyist mech mods. The cig-a-likes usually don't get enough juice to the heating element so when you're puffing a lot (16 consecutive 3s pulls) you end up burning the wick.
