I can't wait to get mine back and they don't even arrive to the modder until Monday
I made the following mods already:
Remove lower oring (I use a piece of Kanthal and wrap it around the oring along the bottom so it goes under it then pull up on the Kanthal and the oring slides right off). This makes the top much easier to remove but still holds it plenty tight.
Replace Allen screws with some aftermarket (or genuine) RM2 screws.
It is a compact (shorter than RM2) robust SS RBA that is easy to build and vapes every bit as good as Chalice / RM2 / Aero BF.
My new favorite, even if I had to live with high feed holes. Replacing those Allen screws is a game changer on it
I will add that I miss using and love RM2s, but I'm on a no brass diet
Prolly sell this aero on classies once the cyclones get home
