The bing is fantastic, love the piece. I don’t love the ROOR bowl it comes with, so I purchased a Hisi 14 mm bowl to use with the piece. This size was listed online for the joint. Once received, the 14 mm Hisi bowl does not fit. Looks low an 18 mm joint and not the 14 mm that was on the listing. Other than this issue, I am very happy with my order and the gift that came with my order.
