I got a new Baby V2 tank the other day but haven't tried it yet. So far these things only have three coils, all mesh. I noticed a few things when I unboxed it. This tank doesn't have a 810 drip tip. It's more of a Cleito style slip off tip. The fill port doesn't have a gasket in the way. The gasket is above on the top piece. The coils are very similar in size to Prince coils. The bottom is the same, but the top threaded hole is slimmer. I screwed a prince coil into the base of the V2 piece no problem and vise versa. The glass pieces this tank uses work for the Fireluke Mesh tank. I've switched them around to make sure. The Smok glass is thicker and seems to be better quality.
