It's OK but much cheaper when purchased un assembled
on March 30, 2012
I purchased these filters for ease of use, because I need someone to watch my fish while I'm away. Just pitch it and install the new one. The only reason I only rated this filter bag a 4 is if you don't mind taking a few minutes to pour in the charcoal and rinse, the box of 12 un assembled filters are about the same price as these 4. These ones are custom cut to better fit my filter 'holder', but the un assembled ones are more squared off at the bottom. They don't fit quite perfectly, yet they still work just fine.
