also what are you using it on, as the weight issue is kinda null when using the types of mods most of the people I am around use
Oy... I'm not certain exactly what I bought them for. When I started vaping I liked a harder draw, so I was always trying to tighten things up. Since I've gotten into slr on gen rba's, I've come to appreciate a looser draw to let the clouds roll. The only mods I had where the Alpha and Omega. So I would've been definitely using it on one or both of those.
I was vaping mainly carto tanks (still do for out and about as a beater), but I also still have this smoktech top coil rebuildable tank in my drawer... If I was to guess, I grabbed it for that when I was messing with it to try and get it right.
Either Way... the thing adds to much weight to the top of a mod imo. And as I mentioned, the lack of a knurled adjustment ring is a design flaw. Nowadays, I like things sleeker also... adding such a device causes you to loss on any "one piece" look you might be going for.
As I said, these are my opinions on the flow control add on from my experience. If someone wants to give it a go, they're cheap enough to try. I only give you the reason mine sit in my vape junk draw.
But back on topic... Overall I think the protank is a great simple device you can throw in your pocket and not worry about. If you're careful not to make ur draw to tight, because with any bcc, you'll end up flooding, you shouldn't have many problems and get a great vape. I would suggest to anyone looking for a clear tank to try one out!
