    CyberPower - 450VA Battery Back-Up System is a decent bettery back-up system. It's suitable for home and business uses. I hooked up the unit to a small web server. Since then, my website is online most of the time. The down time of my website due to power outage has been significantly reduced. It's good investment. I will recommend it to anyone who needs it.

    Reviewed against other major brands and found great performance at a price lower than most. Works perfect for TV, Sat Box and DVD Player for at least 10 minutes. Haven't experienced any longer power outage.

    I needed a UPS to smooth out the power supply to my modem and router, and this product was exactly what I needed. Simple to use, a relatively small footprint, and just the right amount of battery backup for the price.

    We only had this for two days before it showed its great use. We had a power outage at 4:30am, it started beeping and woke me up. We were able to call the power company and start the repairs. I was able to shut down without skipping a beat. It worked great!! So glad we have it!!

    this was a replacement for the exact same product that lasted 10 years ... I don't think I could have asked anything more from a product that protects my expensive equipment in the lightning capital of the world

    Have had a few storms where there has been power surges in the home and this has kept my equipment safe. Plus the battery backup ensures I'm not kicked out of any important items when there is a sudden power loss. Would recommend.

    We live in the great western outback of NV. Power outages, surges and brownouts are weekly occurrences. We have a backup generator that comes on if power goes down but tv, computer shut down (loose work on computer). With this backup everything keeps working through the outage and power switch. Seems to smooth out peaks and valleys of power as well.
