Review on JW Pet Company Aircore Sand Airstone Aquarium Accessory - 2-Inch by Jason Ortiz

I tried the first one and all I got was a few bubbles on the top of the product. So I figured I might have a defective one, so I tried the second one and it did the same thing. So I tried a third, soaked it for a while, then hooked it up to a whisper air pump on my own, and again all I got was a few bubbles at the top of the product. I had no blisters up and down the air stone at all. I took out the third and the tip came out immediately. They're cheap, don't work, don't bubble up and down the air stone. I tried all three and couldn't get any of them to work the way they were supposed to. Not a good product at all. Small tiny 1 inch vents work much better than these. I was very disappointed as I wanted them to create air up and down a 6 inch air stone for the corner of my tank. Buy at your own risk, but I wouldn't do it. Had I not opened and tried to get all three to work I would have sent them back for a refund.
