My sub/top tank mini RBA's have come with the 1.5mm holes you mention, too small unless you wick them incredibly lightly accordingly or they can easily be drilled out with or with a clamp or vice..
However, some came with 2.4mm holes (V2 RBA), but some with huge 3.5mm holes. There doesn't seem to be any rhyme or reason which tank or when they sent them out. This is one area that kanger do need to get a grip, agreed .
Well I was gonna buy a sub tank mini but the guy at my shop told me he had none in but he did have a top tank mini and that the only difference is you fill from the top.
So I went with the top tank. Quite impressed! Not sure about the direct lung vaping yet.
Hopefully I will be able to build some 1.2 coils or something so I can MTL.
Thanks
I'm not particularly experienced in vaping, but I do build my own coils now, but PLEASE watch as many videos and read up as much as you can on ohms law and building coils before you start even trying to build your own.What do you mean by wicking?
