Being an 808 fan, I was intrigued by the Vaporsmiths claim of a 4.5 volt battery, so I ordered up a starter kit and cartos. The packaging was first rate; everything looked great! I charged up a battery, screwed in a carto, and puffed away. To me, it seems about on par with the other 808 batteries I have; their claim of superior vapor production has not proven to be true, IMHO. You do get a bang for your buck (free starter kit with carto purchase), but I'd say it's pretty average. Anyone else tried it yet?
