Excessive wear? They are only a month old. They started out flawless, they are still flawless. Build quality on all three of mine is excellent. There has not been a single drop of leakage from any of mine. Not from the air tight super easy fill bottle system, not from the 510 connection to my atty, and none internal. I never get any joose on my hands or on the mod when refilling or vaping them. That said, there had been an early discussion about some folks having 510 leak issues between the mod and the atty that seems to have ended based on the difference of atty 510 specs not being the same. I have only used my DMP atty's on them, and there is no leaks with these atty's (the DMP's are my favorite squonk RDA's). I don't try to fix what is not broke.
IMO they are best of all my regulated squonk mods for my personal use. But I leave it up to other folks to draw their own conclusions.
