After months and months of daily use, I have come to the conclusion that IMO c vaults are really not that worth it. Considering their design is identical to onyx containers while being sold for twice the price is already unsettling. I'm pretty unhappy considering I paid hundreds for mine and they leak smell on a regular basis. The other night I had one of them right by my bed, near my pillow, and I had to get up and move it elsewhere because it smelled so strongly of dank.
This is not the first time this has happened, I can usually smell coming from the latches as well. With smell being a huge liability to some people I would think they would have better quality control to ensure each c vault is actually smell proof. I can't imagine someone traveling with weed in these, smelling up a car and putting themselves at risk.
I have cleaned each c vault head to toe, inside and outside with iso, so it is nothing dirty on the inside our outside messing with the seal. IMO leaking smell is a dealbreaker, I doubt this could be fixed with me a year later so I probably won't be buying any more c vaults in the future, as privacy is an issue for me and smell leaking is just unacceptable for the price people are paying for these slightly altered onyx jars.
