    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.

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

    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.

    I bought this to keep things on when the power goes out. So far it is working well and I've had no issues. I bought it on sale so it was a good price.

    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!

    hate that it beeps when battery use is active. but it does do its dudiligence. I have my work computer and monitors and internet plug in at all times with the battery portion. the other four side is regular electric. so zoom into picture and you'll see that only 4 ports dedicated to battery which is okay for me. but for others who needs more don't think its all 8. also drains fast. but i didn't expect much from a cheaper brand apc. this is exactly what i need it for. not for longevity.
