I think some of the clone AFC inserts are a bit shonky. I had to fettle the 3 hole one to widen it to achieve a draw that I like. Will be using this over the weekend with my favourite tobacco blend as I feel it really shines with the more 'grown up' juices. For me its a sofa only atty though as its just way too big and ugly. God forbid I was seen in public with it .Dug a clone off the atty stand tonight... forgot how tight it was, but enjoying it for a wee change. Running in TC, no issues.

I took the three pronged pin and used a small file (saw file) to open up the gaps a little. All three pins were producing a draw too tight for me. Id guess something around a .8mm draw. Ive got it to closely resemble my preferred 1.2mm and am really happy with it. You could wrap a it of wet and dry around a ruler and do it that way if you don't have a small file. I think, from memory, you like it tighter though?I ripped apart the shonky one last night but I lost the will to fettle it. I assume you lifted out the upper positive pin and widened the wee hole? Would be nice to fix it so I can use it on the helix cap.
It fell in the latter for me!There's tight and there's passing out trying to get air through it
