I have had mine for a few months now and haven't had any problems with it. I had a leak once due to a piece of grit keeping the trays from seating all the way but have rectified that problem with media bags. I have had the same seating problem on my Fluval 404 and it is user error in both cases not a design problem. The 2075 is a great filter but I don't think I will ever pay that much for a filter again... I am starting to prefer sumps.
