I love the upline ash catcher, it helps keep my bong looking fresh so I don't have to clean it as often. The function is great, it's easy to clean, the bowl that comes with it is a perfect size. The one down fall I have with this piece is it's a little too tall. I bought this with the 8in Grav beaker, thinking it would be a perfect fit, it is not. It's a tad bit too tall to sit flush with the beaker when you set them down together, so I have to keep them separate when not in use. Just something to think about when bundling this piece with a Grav bong! Other then that, it's a great purchase!
