    I bought a Hydor inline heater and when I received it I was rather disappointed in the packaging. The box was creased and torn in corners and the item itself was not covered in any sort of protective cellophane of some sort. Overall the packaging didn't give an impression that this was a brand new unused item. An aftertaste was left that I was sent a used/returned item
