Found out today that the neck opening is slightly larger with the Bubbler. With a bit of force I'm able to push the stopper all the way down to the lip of the stopper. It is a tight and well sealed fit so not to worry. With BB the same stopper only goes down half to three quarters. Same stopper in BB actually feels like it is less sealed - meaning less rubber in contact with the neck side.
