Bests & Worsts Reviews from Amazon

First, let me say I have purchased numerous (over 10) Cyberpower UPS system, both non-sinewave as well as sinewave. These are excellent units. I purchased this EC850LCD in order to keep a couple of NAS storage devices powered in case of an outage. When it arrived it was obviously damage during the shipping process. When you picked up the box, it rattled terribly. Not wanting to plug it in, since I was not sure what was going on inside, and not wanting to open it, possibly voiding any warranty, I contacted Amazon. I had a replacement in 2 days. Now listen up, especially all you Joe's out there who like to write bad reviews because you jump to conclusions and presume things that are not stated, It is true that Amazon will not accept returns on UPS units that they sell. They obviously don't want to deal with the shipping problems that can arise when shipping lead acid batteries, HOWEVER, that does not mean they will not send you a new one, if yours in damaged or dies within the 30 day window. Amazon never says, as some reviewers would like you to believe, that you are stuck with a bad UPS, and too bad for you. As I said, I received a new one, which works fine. I still have the old rattling broken one which I will properly dispose of. Great Job Amazon, keep it up!!!
