So clearly this is an issue. Not sure I should be drinking from a cracked plastic unit and heating it up Moore not sure that that is caring anything. Got it buy a better material. Thank you.
The bottom part of this unit that breaks off actually doesn't touch any of the liquid/coffee , but doesn't stay on very well either. Some prefer the glass version of Hario, a personal preference, others like the plastic because of its heat insulating properties and retention of heat.
