I bought an FX5 about a month ago on Ebay. It was advertised as new. I had it for a week or two in my tank stand still in the box, never opened the box. I sold it to a member here who basically did the same thing and when he went to set it up found the on the top cover the intake tube is broke off it. I contacted the Ebay seller but doubt he will do anything since he accepts returns for only 3 days. So I will ALWAYS open new items even though I may not use it for a while
