To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The first UPS arrived, plugged it into mains and without turning the unit on it instantly started spewing toxic smoke out of the vents.
After eventually organising an RMA with CyberPower (which was incredibly painful) I noticed that they posted all personal information submitted in the RMA to a page on their global website, publicly available to anyone to read.
After dealing with that and finally getting a replacement UPS, it actually worked when plugged in, but I found it was off-gassing yet more toxic smoke that flooded the premises over time.
When I went for a refund, CyberPower dragged it out as long as possible. So long the selling company picked up the UPS' directly so they could deal with CyberPower for me.
Awesome, worth the price for the peace of mind. Plugged in, installed the software, all done. I'm glad I went for a somewhat higher rated/capacity system rather than "just make it" as it gives me far more time to gently shut everything down if needs be. I am running a desktop PC, 24"monitor, camera, external speakers, usb3 7 port hub... Yes, with all this, I have available some 50-60 minutes of runtime if power goes out. Awesome!
