    Not the greatest quality. Will crack easily if you get it to hot.

    I have had three of these bust but I like 420 science so much, I just keep buying them. 420 science is the best. Their CS is awesome. That’s why I keep buying from them.

    Replacement

    It doesn’t quite fit the same as the original one. The diameter of down stem seems a bit smaller. I only noticed because the lack of suction on the gravitron. I had to put tape around the downstem to make it a tighter fit, otherwise, the device wouldn’t function as well.
