I have had a bad experience with an Amazon return. It was a tripod that had broken parts on it (Amazon does not know what a functional piece of equipment is, so they guess). Luckily, I was planning on removing that part anyway as it wasn't needed for the antenna system I was building. That said, I also had a similar experience with a light system that was "new" from Amazon. Again, the part I wanted was not broken, so I just took off the light and can now mount my mag loop antenna on the rest of the stand. BTW, this second one was an outdoor light from a Chinese manufacturer that if they were truthfully named, would have had a brand like CheepKrap.
