    Works well, with a house that has old wiring this is a must to prevent loss of documents and corrupt files.

    Not impressed. I bought this as a backup for a CPaP in case we had a power outage. The first time, about two months after I bought it, the battery lasted the 6 hours the power was out, however, the next time a year later, it failed completely

      Hello Loomex, This product is not designed for use with medical equipment. We suggest contacting the supplier of your CPAP for suggestions in that regard. Concerning the behavior being presented by the UPS, it may have to do with the internal battery. If you would like more information please reach out to us at 877.297.6937. We hope to hear from you!

    DO NOT BUY THIS PRODUCT, IT DOES NOT WORK

    Unfortunately a product like this only gets tested when the power goes out, and that didn't happen before I could determine that it didn't work. I needed it to be able to support a home link system for the 30 seconds it takes for my generator to kick on in an outage. That happened today. All it did was sound a high pitched alarm, and my device shut off with no power to it. Worse, I had to turn off the alarm, whose sole purpose apparently was to announce that it doesn't work. And now, it is ten days past the point where I can return this piece of garbage to Best Buy for a refund. Don't get taken like I did, DO NOT BUY THIS THING.

    This is a good UPS, but it does not seem to last as long as an APC UPS.
