Title: Piece of Junk! Awful customer service!
Review: I purchased this product, installed it an aquarium and it did not work. I followed the directions with the packaging and contacted the manufacturer. I only got a voice mail message saying that they would call back within 24-48 hours. I never received a return phone call. Amazon was good about accepting the return, but I had to pay for return shipping on filter accessories that I ordered with this unit. This problem is not with the Amazon retaler. It is a problem with Penn-Plax, the manufacturer. Buyer beware!
