It's the only option for adapters to work on 808 autos. In my months of research (and I mean months), this is the best I've found.
Baditude has already mentioned the 808 carto-tank option. If you don't want to bother punching your own, Smoktek sells pre-punched cartos and the same adapter as MadVapes. So does V4L.
Yes, the option sucks. But it's the only game in town.
