You are probably looking at this product because you are looking for a good and affordable air vent. Well, it's definitely cheap. I had concerns when I saw how much green "sand" was scattered inside the packaging bubble. They crumbled and crumbled as I put the tube on. I had to detach the hose from one to adjust the length and the plastic nipple popped right out of the rock and was beyond repair. Those that aren't broken work, but the bubbles are much larger than other stones. They "pull" the air out of my denser air stones. When you connect multiple devices to your airline, they use a disproportionate amount of air. The price was very cheap but the quality was the same. Definitely recommend looking elsewhere.
