    Solid product and price. Works as advertised, got to test it already this winter! Half the spots are battery plus surge protection, the rest only surge protection.

    Using it on an electric recliner chair, after a neighborhood power outage made it difficult to get out of the chair while it was fully reclined. The battery backup allows the chair to be closed so I can get out.

    Nice and compact. Good price too. Replaces one of the same i had bought about 10yrs ago. This is smaller and lighter in weight and does a better job

    This backup battery/surge protector is perfect for my needs. My laptop has some backup protection. This device provides additional backup protection. This device also provides protection for surges in electricity which can occur during a rain storm. The CyberPower - 450VA was the perfect choice for my needs.

    I should've purchased one of these a long time ago. I has already been tested. Held power with no issues. I was able to save and exit what I was doing with no power loss to the computer I was on.

    Honestly this was the best $50 I've spent in years. I currently work remotely in costa rica and the power goes out ALL the time. This little baby keeps my modem and therefore the internet up and running non-stop. Its a life saver.

    does what it's supposed to do. So far so good. I used to use their major competitor's UPSs but they started having problems so I saw good reviews on CyberPower and they're good.... so far, and with a better price.

    I needed to either buy a replacement battery for an existing UPS or, lo and behold, I found this. It was a little more money than a replacement battery, but knowing technology changes, I decided to replace the UPS instead. I'm glad I did. Somehow, this is the smallest UPS I have owned and at no loss to the number of outlets or VA. Definitely a good purchase.

    This is a great little battery back up. I personally have four different power supply back ups, running various items in the house. We have multiple larger battery backups, running the PCs and monitors. We also have battery backups on the fiber, Internet as well.

    A very well made and solid device. It worked, as instructed, perfect the first time it was powered-up and has done so for several months now. Twice, when the power at my residence went out, it protected my expensive desktop computer and monitor; no interruption to their operation at all. Very recommended indeed!

    Unit is reasonably priced and has a number of well-spaced outlets. The hard thing about writing a review on a UPS is that if it works well you can't really write about it until its needed, and without a power outage so far I don't, but for a short-time, low capacity application this works well

    I made this purchase looking for a battery back up that would not break the bank but would protect our periphals from surges which happens a lot here. The battery back up system came highly recommended and has good reviews. So far we are well please and have bought 3 more.
