    I bought this for my home NAS server, so I don't have to worry about power outages corrupting my system, while living in the lightening capital of the US. It integrated with my FreeNAS system out of the box with no issues except picking the right driver. For those interested, the driver to pick is: Cyber Power Systems ups 2 Value 600E USB (usbhid-ups).I I can't speak to hire will it works for PC or Mac or what the software is like, as FreeNAS has UPS monitoring built-in.

    Perfect for those little power blips to maintain internet/router/wifi connection. Great compact size of unit. Plug is bulky and at awkward angle. Big plus to have USB ports.

    I've over the course of several years bought these units, APC and Tripplite for my home. I've found that these unit's batteries have a better longevity versus the other 2. On average these batteries will last 2-4 years with a small number lasting more than that. I also like that they've included in these 2 units (2) 2.4A USB charging ports thus freeing up 2 more of the outlets! That is a great bonus and much appreciated.

    I put this UPS on my fish tank so the heater and filter can run for about 30 minutes during a power outage. Power went out and it worked !! Outage lasted about 45 minutes and the battery still had a few minutes left in it. Not just for computer and electronic equipment !!

    Great little UPS backup for protecting my music recording gear and outboard devices while in a session. I protect all of my studio gear from under-voltage, dropout and voltage spike damage. This is just an addition to my other UPS units that keep my gear protected.

    I use this supply to back up my security system power. It works as advertised, but even though it has eight outlets, only four of them are battery protected. The other four are just surge protected. The main problem is that the four outlets that are battery protected are all so close together that the equipment that I have (router, cable modem, etc), cannot all plugin together because those items have small power blocks that cover at least one extra outlet. The power supply should be redesigned to use some of the blank space to space out the outlets so that it will accommodate power bricks.

    This was bought as a backup for my cable modem and router.Tested it by unplugging it from the wall and it kept both devices going for 15 mins upon which I plugged it back in. Had a power outage and it kept devices going for at least a half hour (longest I have had a power outage for.) Great price for the backup and safety it provides for smaller devices!

    Just simply works. It literally disappears until it saves your butt by just simply working. Too much tech today needs messing with and this is exactly the opposite. Just. Plain. Works.

    I'm glad I bought one of these. I needed one in case of power surges and outages that seem to occur often enough. I use one for my PC, monitor, lamp, and printer and to charge my cell phones and chargers. I has so far worked exactly as it is supposed to work, I have two of these to use in two different rooms for my other PC's and lamps.
