Whats up everybody, I'll be recieving my first Roor bong sometime this coming week. I'm so excited, it's going to be a German Roor Blue500 series in 18.8 joint size, also going to be ordering the German made Roor diffuser soon. Will have pics up showing it in all its glory plus many milk shots. Picked up at EDIT for 150 usd shipped. Thinnest glass of all Roors being 3.1mm. I've got a few buddies that own German Roors with diffusers and I have to say that anybody that says Roors are not worth the price simply has not had the opportunity to hit one of these works of glass art.
