You can use the Sidesho atty from ModernVapor, but you must use a Sidesho cart with it.
Good news is that the Sidesho cart can be bought in blanks (Blu cannot, you must recycle those more expensive pre-filled ones) and they hold a lot more juice than the Blu does also.
If you go that route, be sure to use the 25% off discount code posted in their forum!
Yes that rite now is my first choice and maby one 510 atty people say those fit as well.. but rite now its mainly the sidesho or somthing like it.. J108 rite?
