Barely works at all.
When this product is set up in the buckets that are sold for it it works kinda. Even with a massively oversized air pump i barely got any water flow at all. A few drops here and there thats it. I tried modifying the kit by making all the fittings tighter and it improved flow a little bit but not enough to use. If you want to upgrade your buckets to something bigger they dont work at all. I ended up tossing out most of the kit and just piping the drip rings into a few super small powerhead pumps made for nano aquariums and now they work famously. If you want to use these drip rings i suggest just buying the drip rings and resevoir level indicator/drain tube and a small powerhead and going that way.
