    Works fine and gives me comfort that my pc may be protected. Easy to use, plug and play. I need a lightening strike on the power grid to be certain though.

    This CyberPower Back-up System replaced an APC unit that had run out its life. This new system was easy to install and connect the computers, etc. All is working great.

    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.

    This is my first at home battery backup but it stacks up a lot better than any previous brands at work thus far. My favorite is that it has 2 usb ports for surge protection in addition to 8 outlets.

    This unit has 8 outlets so I can protect DVRs and more. I suggest that you always record the serial number when unpackaging. It is needed to register the product.
