Pros RooR GLASS Best taste . Cons none conclusion i use this with my 18 inch RooR 9mm, 5.5 inch allows me to use very little water and get really great hits

So... I actually bought this item and realized I need something smaller for my Roor (3 inch) after it arrived. However, it was such an easy experience purchasing the piece, that i'm just going to hold onto the downstem and look for something that uses it. Been eyeing a few pieces on 420science =)
