Not very good fitting glass is what you pay for. I happened to break my glass too often. The down stem provided accentuates the poor fit, I replaced it with the one that survived my last breakup. Improving the fit but far from perfect. The fact is it’s highly functional. If you are a perfectionist you won’t be happy. I’m not part of the stupid wealthy so I’m happier knowing I can do more with the money I save on perfectly cut titanic rigs destined to sink with the first iceberg strike
