### ⭐⭐⭐⭐ Great addition to filtration; cut size is a bit inconsistent.
*by 4***Y on May 6, 2024*

Filters are like printer ink cartridges. That is where the money goes. These filled a great need for my home aquarium. Reusable filters are a need in our turtle tank. When first removed from the package, they are stiff, and misshapen. A quick rinse under warm water expands them and returns them to their rightful shape. I retracted a star due to the cut. The filter is normally trapezoidal in shape, and while a couple are, most are not even square. They seem to be cut at an off angle. In the end, they do they job, but with the incorrect cut, they tend to bow, or sit in the filter housing at a weird angle potentially leaving gaps that tank waste can get around. A small issue, but quality control could be better.
