OK...
I'm using this and having success with it. No cleaning poly, burnt taste, straws, paper clips, etc., just plug & play. It favors the VG mix but PG seems to work too (maybe not as good as the VG though). It has only been tried (by me) on a 510 because thats all I use.
These are three 1/2 brass pipe screens shown below.
