Okay, let me begin by saying this. I’ve had multiple other sized water pipes and this one beats them all. Super smooth hit. There is a fused down stem so it is non removable. That is a plus because I would constantly break down stems cleaning my pipes. Also the perc at the bottom cleans the whole base when filled from the top, due to the shape of it it splashed water up the sides of the pipe (Huge plus) definitely worth the money!
