When received the cover/cup was missing. I called Stanley and they sent me a new cup. When I installed the cup you could only tighten it part way and then it would pop off. obviously the threads on the vacuum bottle were messed up in manufacture. This would also account for why the cup was missing in the first place. I returned the item mainly due to the poor workmanship.
