    I like the arrangement of the outlets on the top, and the flat shape of the product. It is space-efficient and is perfect for my internet router and hub.

    Needed a simple UPS for a client. You're not going to solve world hunger with this bad boy. But you will be able to turn your electronics off safely during an outage.

    Excellent Backup

    I love in an area that sadly has too many surges and this thing has outright saved my work on my PC too many times to count. The loud beep will let you know it’s served you, it’s intense, but I’ll take a little shock knowing my gear is protected allowing me to save and properly shut down. This has a 15 minute back up, so you have plenty of time to finish work and save. Worth every single penny.

    Good for light loads I’m using it for my laptop music studio (even though it’s running on battery) the surge protection is an added benefit. It allows me time enough to close a project and shut down properly since I have external drives and peripherals that need to be gracefully shut down. Don’t expect lots of run time with this one
