These work as intended. They are nice and heavy so they sink and stay put unlike some other smaller stones. I am happy with them. No complaints.

Love these, worked immediately and weighted, so they stay on the bottom.

I like the quality of these air stones. Solid, well-built. They are also HEAVY so they stay put wherever you place them. The bubbling action is great - fine bubbles aerating the pond. Fish are happy. Kind of pricey but probably worth it in the long run.

Works great but all the bubbles seem to come out on one side more then the other, but I might be pushing to much air so its probably user error.

these things are huge, like people say, lol. they work great. a large pump is needed to drive a single stone. I love the weight, am sick of the lighter ones being moved around, floating, whatever. they are good quality. there is only 1 inlet to each stone (not dual inlet). i have 2 in an 80 gallon aquarium, honestly one would be fine.

I had high hopes for these bubblers due to their size and potential, but the performance was disappointing. Both stones only bubbled at the front or the ends, almost as if they were leaking. The middle portion produced minimal or no bubbles at all, which made the overall effect underwhelming.

I love the shape and size of these air stones. I am using them for hydroponic gardening applications and they disperse air as they should. Having bought a pair more than a few months ago, I ordered a second pair.Unfortunately the the air stones arrived damaged. Amazon shipped them in a bubble envelope which doesn't protect them well. One of the stones had the air inlet severed off; the second air stone had a manufacturer's defect where one of the end-caps was not fully seated when it was sealed. I can see a hole where air can escape instead of properly diffusing through the stone.I requested a replacement and received it again in a bubble envelope. Upon opening, one of the two air stones was completely broken.So far, I am 1 for 3 on receiving a functioning product. If you count the # of air stones total, 3 out of the 6 were not damaged or defective. It could be bad luck on my end, or a combination of rough handling at some point prior to receiving the item and the cold weather causing the item to be more brittle.

I've used it for a few weeks now and the bubbles are amazing.
