Review on Aquatic Life Pre Filter Replacement Cartridges by Drew Diaz

The high pressure fittings on these filters are made of plastic and the threads can break. O-rings in the cartridges are rubber, they can fail. If you're replacing o-rings or fittings, you can buy a new unit for $7 more than this very listing, but they won't even ship you the items that wear out over time. I'm really disappointed, for $45 I expect the cartridges, diaphragm, cartridge o-rings and flimsy brittle plastic fittings to be PRE-INSTALLED on the cartridges. You need to improve your game or inform customers about the device replacement. Honestly this kit is a waste of money, I had a small leak in two places even though I did everything 100% right. Take my advice and just buy a new device. End of the story.
