I ordered a backup 510 Wetbox a couple weeks ago after my other one pretty much came apart because the sealer used to put it togther broke down over about three months of steady use. The new one has the new, white, sealed activation switch and Missy now uses a black, shiny type of sealer that drys hard and that appears to be able to reist the effects of PG. The old sealer was an almost clear, rubbery silicone that apparently broke down in the presence of PG.
I use my Wetbox with the CE2 R4 reg size syringe mod with only the center plug left in the carto. It will leak if laid on it's side but I keep it upright. I just tilt to the slot sides to wet the wick if it gets dry. I don't squirt juice to it but it's available if the carto runs dry at some point. Added insurance, hehe. I also peirce two small peices of paper towel and slide them down to the base of the needle to absorb any juice that may drain down if I do squeeze the bottle.
Between these two mods I have an excellent vape system going.
