The holes are too small so it clogs easy

Great love it best airflow in bowl ever im buying one for every male fitting i own

I accidentally bought the wrong size, and contacted GRAV about possibly returning the item so I could reorder the correct one. They actually told me not to worry about it, and ordered the right size for me and had it shipped within hours. Fantastic quality stuff and fantastic quality service.

Seems like a great quality piece, but doesn't fit my male stem (which I measured and double-checked online to be 14mm)

very bad bad i paid for 2 day shipping and you guys went and bought the ground shipping and it didn’t get on time. Plus you guys didn’t even tell me you guys were wrong and just refunded the money back with out telling me what happend Plus guys only gave me the shipping refund when i totally deserve more for the inconvenience
