Yeah, i was the same bob, a couple of go`s and it was rockinThe chimney is a bit of a pain, as is filling them ! Have to fill really slowly, or it just comes back up, and all over your hand
I have also started plugging the top cap with some tissue when filling, and that seems to help !
Don't have that problem, if the bottle has a stubby top like the MBVs, I just use a syringe (same sort of thing happens with the KFs if you bottom fill them)
