I recently purchased the Hastur RTA. While this tank is great in so many ways I cannot get over how finicky the top cap is with closing. I will literally have no issues with it for days on end then suddenly spend 1-2 minutes trying to get it back on. It has one of those bayonett style twist and lock style tops and if the notches on the top cap are not perfectly aligned it will not close. Essentially like they built the tollerences too tight and/or didn’t graduate the transition from the notches into the rail enough. It is almost a deal breaker. It is not an option to get stuck out and about with a freshly filled tank and no way to close it. Urrg! Does anyone have experience with this?
