If anyone knows of a uk vendor who might stock the Artery RBA Coil for PAL II/ Pal II Pro, I would be pleased to hear, seen it at Heavens Gifts but never purchased from them before.
I like them, I like them a lot, but I also like an rba options, both for the economics and future use, when coils might not be available.
Anyway, this pic explains a lot, the Artery Pal 18650 kit lists 3 bases, FT lists the width of the rba as 15.2mm, I thought no way, but yes, it looks about right here.
