    Got one of this as deal of day, I should got 2. The size is good, not heavy and the plugs are on a way that don’t interfere with each other even with block adapters. Excellent product

    I have bought several of these, though not for the back up battery primarily. I needed clean filtered constant power. This does a great job a great price. You won’t be disappointed.

    This unit is great, I have my computer, monitor, printers scanner, etc plugged into it. If the power goes out I don’t lose anything, which is very important to me.

    CyberPower battery back-up

    I bought to replace a 6 year old one of the same brand that stopped working. Order process was simple and device arrived when expected. The outlet orientation was rotated 90 degrees from prior the prior unit and it made 'plugging in' a bit of a jigsaw puzzle. Orientation makes sense if just a plug but 4 of my 7 devices had mini-transformers (bulkly) instead of a pure plug.

    My old cyberpower back up system lasted 4 years. The battery portion of the system quit functioning. I was happy with the way it performed so I replaced it with the same unit.
