I purchased many things from Amazon, and in general, I have been pleased. The prices are usually very competitive and the shipped items arrive intact. But the other day I ordered a Fluval E300 heater. When it arrived, it was obvious that the heater had first been delivered to another person who returned it. The box was crumpled. There was no cellophane around the box. The twisty was off the power cord which was unwound. I sent the heater back.
