So, $240 new on Amazon (recently $220). Is it worth 25% off to get a reconditioned with a shorter warranty?
The one I got was like new. I have several of these and unlike APC they have lasted without any issues.
In the last 10 years or so, I’ve purchased at least half of my several UPS units as refurbished items from the manufacturer. CyberPower replaces the whole battery unit as part of their refurbishing process, and the quality has been nearly new in most cases.
Given their track record for me, I like my chances. As was stated, I would tend to agree with @davidbspalding ; I might not trust all brands in the category the same, but for having over a dozen of these things in use (varying models, but all similar enough - GX, PFC, Rack mounted) they have all done great.
Hope that helps. But by all means, if the extra warranty gives you peace of mind, then go for the new one. No judgement here.
