Okay I've got both a V3 and a V4 both black, I've sorted the leak issues,love the taste, but the V3 just doesn't hold enough liquid for me, any one know if the base will screw straight into the FT sku 1692100. If it does i've a nice size dual coil tank , and if the other base fits the orchid ,a miniature (nano?) . So a Orchfun and a kayid, anyone tried it.
