It doesnt necessarily need to be a "scientific process." It is just the little things that count, liek a good air to water ratio, thickness of the bong, diffuser, ashcatcher, all of these are better quality than a regular old acrylic p.o.s.
greendragon420 Reviewed by greendragon420 on . Getting a ROOR Bong Been thinking about getting this bong offline. What do you think of it? I was just wondering if anyone else here has ever ordered anything from this site and is it safe to order something such as a bong overseas. Site seems legit to me but always have to be safe. And before anyone says just go to a headshop and get 1 I'm not old enough to go into 1 yet but have a friend who will order it for me all i have to do is get the money. Feedback would be greatly appreciated. Rating: 5
