It started out with good air flow and a slight whistling sound. As time went on gone with the smoke got thinner and the bubbling on the hookah got softer. Tonight I found that right where the hose meets with the handle, about an inch away, under the cloth wrap the actual hose material is completely split open circumference/diameter-wise, not long-wise. The airflow is now horible because it's a big gap. I've had the hose maybe 3 weeks at the most. I have to hold it tight and at an angle to allow it to work. It's uncomfortable. I'm going to try to glue it or something. Don't waste your money. I'm a little ticked off that I bought something and it's done for in 3 weeks.
