I was just given a w3 which was purchased from here and I understand completely why I was given it.. Why in hell cant anybody clone a top cap correctly? 4 slotted holes.. You would think when a company makes a 4 coil dripper that sees 4 slots in the deck that SOMEBODY would ask 'why are there only 2 slots in the top'. I get it.. YouDe isnt 'top of the line' but if they cant properly copy a 20.00 dripper why would people spend bank on an expensive copy?
