My dumba** poured alcohol in it to disinfect it...
Wanna guess what happened? v_______________v
Yep, it made the glue between the nipple and tubing(inside) to disintegrate.
So when I peed, pee would get stuck in the cracks.
I used a lighter to melt the plastic and make it stick together again.
So yeah.
DO NOT USE ALCOHOL TO CLEAN IT!

Other than that, I think it's great.
