I did not realize it was possible but these both stopped working in less than a month. I tried cleaning them and using a stronger pump but they simply wouldn't bubble. It was a waste of money for me and I will never buy them again.

I bought two. One of them works great and the other one only bubbles from a little more than half the stone, which other reviewers have also said. Still plenty of bubbles. These are fairly large, which I was happy about. Suction is great. My mystery snails like to climb on them. For the price, can’t beat it honestly. If they stop working, I will update my review.

As the title says, these provided a significant improvement in the diffusion of air into my DWC solution. Prior to buying these stones, I used a single 2x4" cylindrical air stone per 5 gallon DWC bucket, on a total of four buckets, with all of them being supplied by a 110lpm air pump. I did not realize how underrated my old air stones were until swapping them with these, which are rated to function (4" model) optimally with a supply of 12LPM's of air per disc. I have since ordered a second set of four 4" discs with two being at the bottom of each DWC bucket, for a total of 8 discs being hooked up to the same 110lpm air pump. The difference in the amount of bubbles produced despite the same amount of air being pushed through the same amount of DWC solution has been absolutely astonishing. Out of the 8 I ordered, there are a couple that appear to not function as evenly in regards to diffusion as the others; This difference has been so minor though that I do not see it being worth returning. If you match your sized air stones with its minimum Liter per Minute of air requirement, your likelihood of receiving subpar air diffusion is quite minimal. Many people are unaware at just how much air these little guys are rated to handle, and don't understand why their 20LPM pump divided to 4 different air stones aren't evenly diffusing. Certainly not all bad reviews are a result of this, but I do think that it is often overlooked and matched with a general notion of not needing a lot of air or not understanding how much air is even optimal to begin with in DWC environments. (FYI: 1LPM of air per gallon of solution is, generally, considered to be optimal so long as water temp doesn't rise too high.)

I've had great success with these stones, six so far. They work like they should. Initially I was worried when I saw them only giving air from one edge of the stone, but when I hooked them up to a real pump, they churn out bubbles from everywhere. 4w is really about the minimum to get good air flow through them, 6 is great, 10w makes them unbelievable.

Great stones. Using them for DWC in 5 gallon buckets. Vivosun air pump split off to 3 at the moment and the buckets are churning with bubbles. Great air stone for hydroponic application due to shape and air flow. Worth the relatively high price.
