Yeah I was reading up on the "smell" of bronze generally, there's quite a lot about it. Then on reexamining the smell I can detect the part of the smell that's weed and the other part which is from the bronze.
I enquired with VG and they said there shouldn't be any smell and they'd exchange my unit, but I wanted to check here first if others had experienced it. I think I'll keep my unit, took two attempts to get it here the first time, I don't need to wait even longer
I'm really enjoying my bronze Sherlock generally, one thing though you have to be more careful about combusting. Because the vapour is cooler and smoother than with my other VGs, I've been borderline combusting on a few bowls. But I guess that's what they call "a good problem"
