I've just received (from FT) GT-T V2, Tank, Acrylic, Red (top refill) / SKU:
2252403
I gave it an appalling review (since deleted it seems) as I just can't get it working at all.
It arrived with the central chimney push fitted into the tank. I checked the red O rings fitted nicely into the GT-T's top cap - which they did and were good for length too. I assembled everything, closed the AFC and top filled. Errr.. I didn't use a needle filler

, I just rammed a skinny nose juice bottle against the fill O ring and squeezed. It leaked, badly. Juice poured out of the AFC ring. As I thought it would.
I turned the tank upside down with the top plate (on the left in the pic) still on ('cos I'm not stupid

) and started unscrewing it. Half a turn and the remaing juice in the tank poured out. That push fit chimney had detached from its seating. I hadn't anticipated that.
I've just glued the chimney in place, while it dries I thought I'd just ask:
Has anyone used this thing successfully?
