    Great product. Cyberpower makes quality stuff. I wish I had checked at Costco first, as they had the same price for the next-step-up product (680VA versus 450VA or some such). Still happy though.

    Recent outages, some lasting from a few minutes to several hours, cause me concern for my newly acquired all in one. It has no auto shut down functions, but will give you time to manually close-out and shut down.

    Working great! Always use a Battery Back-up for our computers and printers. Insurance in case of power failure or a power surge.

    Does what it is advertised to do. A review this early is less meaningful. Hope to do one in 2 years

    Backup batteries are getting smaller and lighter. This one has plenty of places to plug in. I use them for my computer and for my TV and related equipment.

    This works as expected, I had another UPS same brand previous model, still active after 5 years no issues, this one more powerful and has a smaller footprint was perfect for concealed location. I like I can install and forget is there.

    This is great for powering a home surveillance system and power supply. Don't plug your monitor into it because it will drail the UPS faster!
