Do not like it personally. Easy breakage considering the angle on how you will need to press the Cera on the glass piece — it will break fast. So it is the wrong direction. If you take the Cera and press 'down' on the glass joint your Cera is working with your piece's angles. Far less likely to break.
EDIT same topic: For the life of me I can't see the advantage of using the Cera with a glass bubbler. I tried it and all I can say is that it was not as good as a plain old Cera which tastes far better alone. In fact I have put all my glass away. Just sayin'
I like using it with glass when the UFO mouth piece gets uncomfortably hot. Great for group scenarios. Solo use is usually with just the Cera.
