Product review (4 stars): It's a filter allright.
There isn't much you can say about a replacement filter. It does its job, and it does it well. I'm giving it 4 stars because I had it running for +- a month, and I already have that "dead fish" smell that comes out when it's time to replace the filter. But once again, there isn't much that can go wrong with this! It comes neatly packed, so you just pop it out of the box, get it wet and it's ready!
