    In our neighborhood, power goes out during every storm, even if only for a few moments. We have several computers working for our business and even a short outage could cause a disaster! We have had no problems since we bought the product.

    Everyone should have one of these battery back up/surge protectors on their computer and all home electronics. It will pay for itself during one storm with a power surge. CyberPower is a good product with a reasonable price.

    Battery backups are a must, especially in CA with the rolling brownouts and the public safety power outages. Kind of a no brainer when trying to keep your equipment operational when the power is out.

    Bought for NAS storage device in my RV. Connects to NAS via USB so device shuts down correctly in the event of a power failure. Great for single smaller devices.

    My previous apc model bit the dust during the last outage. I’ve never bought cyber power before, but this unit is the best size and shape for my cabinet. I hope this protects my kitchen entertainment center for as long as apc.

    An inexpensive but very reliable UPS. Cyberpower has been around a while now, and I find it to be as good or better than my APC units.

    Bought it one (1) year ago and it is still working well. In many instances, while doing important work on my computer, electrical power was lost and the battery back up saved my work

    My wife uses a CPAP at night. If the power goes out she nearly suffocates until she wakes up in a panic. This product saves lives as well as data.

    My old battery backup died right in the middle of a project. All the beeping and frustration! I calmed down, went straight to Best Buy where they had exactly what I wanted and carried on with my project. Nice system.

    I made this purchase after a similar product I had shorted out. This battery pack is working well and well worth the price I paid which was reasonable in comparison to other similar products. Very pleased with this item.
