My AC9 arrived today and the finish of the atty. is a PERFECT match to my SS-M Roller. Absoluetly perfect match! Also ordered a hourglass drip tip from ALTSMOKE that is also a perfect combo. It looks stunning on the Roller! Loving it!
There is about 1/2 mm gap from the Roller to the base of the AC9. Seems to me that the 510 threaded base of the atty. is a shade too long. I have the center pins adjusted as much as possible, just seems that the atty. threads need to be sanded or milled down a tad.
Rolled a SS mesh wick, put a 5/4 28 ga (1.1ohm) coil on , filled with Grants Vanilla Custard and found vaping bliss. One note of the AC9 kit is that the pre-cut pieces of mesh are tiny. I used a pre-cut piece for my wick and it is a straw. Vapinaze used to include pre-rolled wicks in their kits; not now. Seems that they are skimping out on the mesh included, but, it works.
My AC9 did screw into my Roller recessed brass connector but it took some persuasion. My connector was somewhat faulty to begin with but it did finally accept the AC9. If it gets stuck onto the atty. threads when removing, make sure to wrap the brass with a wash cloth before applying a channel-lock or pliers to remove it. The brass connector lips are really thin and bendable.
I'm really happy with my Roller, great little mod! The AC9 is a perfect match to put on the top.
