Good little units 5/21/2020 1:40:55 PM

Pros: -Easy to use
-Small enough to be out of the way
-Good number of outlets on it
-Easy monitoring software

Cons: -Noisey when engaged
-Could use more power for price

Overall Review: Purchased two for when brownouts happen and it did a few days after they were installed. The software told the main computer to shut down and that allowed for no issues with the systems power supply. The second unit protected my new TV. Last one's power supply blew due to a brownout and I was able to turn it off and all the electronics attached.

When the power went out, the units started beeping and didn't stop until they were drained. This is the only annoyance, for it a brownout happens in the middle of the night they will wake up from our sleep. I could find nothing on the unit or in the managing software to turn this bothersome feature off. It is the biggest thing I would change.

Excellent product, the worst warranty claim 3/27/2020 9:01:06 AM

Pros: -Excellent product, works as intended, low failure rate

Cons: -Support and warranty claim system is the worst among them all

Overall Review: I have around 100 units of this in my organization and recently one of them failed, still under warranty, tried to claim my warranty, and it has been almost two months and I just received one answer from a member of the sales team implying that I'm dumb. CyberPower Tech Support Case 00154088 - [ ref:_00DC0PetO._5000h1ev6rf:ref
I will no longer buy products from CyberPower period, I'll let company's legal area deal with this.

Great So Far, Have Yet To Fully Test 8/7/2019 6:49:10 PM

Pros: helpful spacing of outlets for transformers, long cord, the software I got from cyber power's website installed on Windows 7, that same installer worked on Windows Vista as well, Linux Mint 19 shows how much battery life is left and detected it right away without software, non power backup outlets I use at times for PC speakers, a laptop charger, a AM/FM radio and, a small table top fan

Cons: The green led is always on which can be bothersome in a bedroom, the software will use some memory and Internet send and receive in the background in Windows, the application window is one size

Overall Review: I have this for two desktops (one at a time) about 225 watts each and 2 27" monitors about 25 watts each. When I plug in the desktop from 2014 I notice the heat from the internal power supply more. I don't know why, perhaps it was used to more or less voltage before. When you first set it up you will notice some significant beeps. With nothing plugged in I unplugged it and it started beeping as expected. What I have yet to test is both desktops at the same time and unplugging it with a desktop and monitors on. This is my first UPS that I have purchased. I have more peace of mind knowing if the computer is on and a wind/snow storm disrupts the power there is time to properly shut down.
