Review on FREESEA Aquarium Submersible Water Pump: 550GPH 30W - Ultra Quiet Mini Side Suction Pond Pump with 6ft Power Cord - Perfect for Hydroponics, Statuary, Fish Tank by Sasha Holmes

Ordered twice - the first had a split thread in the seam so you couldn't thread either adapter. Damn. Returned, received a replacement the next day - cool! Well, this one broke too. It's functional and I need it so I can't return it AGAIN, but hopefully it still has enough life to justify the cost I'm eating for it. If you need a pump as a last resort I would generally try to see if it works for you, but if you need reliability and timeliness I would look elsewhere.
