The HiSi 6in Bent Neck Beaker Bong has smooth, cool airflow and feels great in your hand, but it is a bit pricey. Despite not being that big, it feels sturdy and comfortable in your hand (love the angled neck and wide mouthpiece). It comes with HiSi's 14mm Drain Bowl ($40 separately) – it's got a bunch of small holes that allow for great airflow but stops material from falling through. Getting an awesome bowl I can use on with other water pipes helped me justify the price. The fixed downstream percolator does a *really* nice job of cooling off the smoke. Also, very easy to clean. The size of the pipe and bowl make it great for one person use or sharing with someone else. Can't speak yet to the durability of it over time, but if it holds up, I think it will have been well worth the price. Overall – this is an excellent fusion of form and function if you can afford it.
