“The zirconium ceramic mouthpiece gives a slightly cooler exhaust, is less obstructive to bud flavour, is easier to clean, and fits cushier than its original silicon counter part.
Well worth the upgrade.”
“Came with the IQC but the rubber gasket is not a tight fit, so it keeps falling out despite being lined up correctly in the groove. It's like .02mm off - so close. It doesn't have any negative impact on the airflow when the lid is closed. Just an annoyance as it goes skittering across the floor periodically when opening up the lid for cleaning or battery replacement.”
“So I didn't buy a spare at all, but I only use this moutpiece on my IQ2. I feel that I get a better airtight seal and feel more comfy using this. I can also easily wipe this with an alcohol wipe and share. I also have a 10-->14 adapter for my glass piece. When I am home I ONLY use the glass piece with this. 100% amazing and go sleek!”
