Review on JW Pet AccuAir Gang Valve - 4-Way: Optimize Your Aquarium's Aeration Control by Alexis Jordan

Weak thing and the bracket didn't open wide enough for my tank at first. It's cool, I just put it on top. Then one day when I decided to remove a piece of air hose from it to replace it, the transparent end piece that the hose attaches to immediately detached along with the hose. I had to screw this all the way down and now it can no longer be used. Perfect! NO! I would buy another one but I doubt it's better. By the way, before this happened, I had only been using this item for about two months. EDIT: Up to 1 star. All the parts holding the air filter tube came loose and it went in the trash can. A piece of complete garbage.
