I purchased a AquaMaxx filter/skimmer from joseserrano off of Ebay. The item arrived broken/damaged. I contacted seller right away and sent many photos. The seller offered no refund or exchange, only to wait and see what Fed Ex says. I offered to exchange for a less expensive protein skimmer and send cash difference and received no response. The seller's communication is very short and poor overall. The seller did nothing and Ebay had to step in and provide a shipping label. The item was shipped back and Ebay provided a refund. I still have not heard from the seller. Bad business and poor communication from joseserrano. Buyer beware!!
