Query: Fluval 404 = JUNK

I have owned a Fluval 404 filter for just short of a year. I have had to replace the impeller and magnet when it fell apart. The rubber "O" rings are now failing, causing the filter to leak. After reading some of the other postings here, it sounds like the filter is not even worth fixing. I am very sorry I bought this total piece of junk. After 11 months, I need to buy a new filter. DO NOT BUY A FLUVAL!
