This thing rips. The double water filter is 🔥 this a must have if you like bongs and bubbler. Don't mind the shipping time as it's free and this piece is priced so good. I would recommend a ash catcher for this to keep it super clean. I use glass screens so material tends to pull through but ash catch will not only catch it it will give you a 3rd filter also. I will be buying more pieces from them.
