I have had one of these since 2008ish. It has been working great! Haven't had to do anything to it except for normal maintenance. Runs quiet as ever. The only gripe I have with them is that the baskets on mine fit really snug and I have broken all the handles that you use to lift them out. Finally broke the last one about a month ago. But for the price and five years of use I haven't gotten out of it so far I would definantly buy one again. I run this filter along with a Fluval 306 on my 55g tank.
