    I have four of these in use right now. That should say something.

    I have owned a number of these over the last ten years. They last their expected live. They don't take up a lot of room, but what room they occupy is well-worth protecting whatever is plugged into it. Right now, I own four CyberPower UPSes of various sizes. One protects my computer equipment, one protects my AV equipment in the living room, one protects my home security system, and the last protects the Frontier FiOS telecom interface in the garage.You can't go wrong with these considering their price.

    Better than APB!

    I have been using Another Popular Brand of UPS for years, I'll call it APB. About 4 years ago when installing a new desktop PC I decided to try the CyberPower 850 instead because the price was better. At about the same time I installed APB to protect my home entertainment system.When power went out during Sandy, the APB unit failed instantly, even though it showed the battery was fully charged. The CyberPower continued to provide power and after automatically shutting down the computer, kept the cable modem and router operating for about an hour, so our wireless Internet connections continued

    Useful Light-Duty UPS with Some Obvious Design Oversights

    My home and home office contain many sensitive electronic devices. We have several personal computers, a PC server, NAS drives, routers, switches, printers, cordless phones, security system, etc. All of these things (and more) plug into the AC mains and are therefore vulnerable to voltage sags or spikes and the occasional power outage. When a person invests a lot of money in electronic hardware, it only makes sense to do everything you can to protect it. That is why I always discourage people from plugging these sensitive devices directly into the wall. I currently have a total of 10 UPS syste

    Highly recommended!

    This has been a very reliable UPS supplying power to a TV and my internet router. I've had it operating for 5.5 years on the original battery, and the battery still tests good and it still maintains power to the router whenever the power goes out and suppresses surges.I also have a CP1500 UPS that supports a PC and associated monitors, which I have had for 12 years, and which continues to work as it should. I just installed a third set of non-OEM replacement batteries in it.

    Great product!!!

    I purchased this unit because at the time we were having electrical issues on the part of our utility company, and I wanted to make sure my electronics were protected. After having used this product for over a year, I feel like I can safely say that not only has it worked well it continues to do so. As this is the first UPS device I have owned I can't make comparisons with other brands, however I have found this one to be easy to use and I really like it. The LCD screen is nice and informative with a single button allowing me to cycle through the status screens with ease. The overall unit look

    Works as advertised

    I got the item 5 days ago. I tested it using a computer running Windows XP and drawing about 130 watts. When I unplugged the UPS from the wall the software reported 100% battery capacity and 19 minutes of remaining run time. Twenty minutes later it showed 25% battery capacity remaining and 6 minutes run time remaining The software (Power Panel Personal Edition 1.2.3) was configured to save open files and shut down the computer when run time was down to 5 minutes. This worked as advertised, and the computer went into hibernation with 5 minutes remaining run time. Also, it successfully saved an

    Great product with exceptional results and performance

    I've had this unit for 5 years now. I live in Alabama and here the storm seasons stretch over six months of the year. In those six moths of the year we have plenty of power surges and outages and one happened three days ago. So as I said, I've had this unit plugged in and charged for 5 years now and during the last serge it proved itself. AGAIN! I have my PC hooked up to it - 1500W power supply, two 1TB hard disks, solid state, 32 GB RAM and 2 GB video. To the computer I have connected two 27" LG monitors, printer, stereo system and large Intuos5 for photo editing. I was stitching ~1.8GB panor

    great ups but software is high on promises and short on delivery.

    First off, I will start by saying overall I'm very pleased and impressed with this UPS. I rated it 4 stars instead of 5 for 2 reasons. the number one reason is that I purchased a 1500lcd for my pc, I liked it so much, I bought this 850 just for my Modem, Router, and Security camera Nvr. then I purchased 2 smaller 850valcd units just for the security cams on each end of the house. well to my Suprise, when the other units arrived, I ran usb cables to monitor all of them from my pc... WA WA WA lol no, unless you pay a hefty fee you can only monitor one, no way to switch between units. I ended up
