    This ups is cheaper than the APC, and is rated the same to similar units, but it has a small battery. Works good.

    Easy to unpackaged and quickly had the old one replaced and new one doing the obligatory pre-charge of battery. The unit seems to be working effortlessly.

    What can i really say about this item? A ups is a UPS, i needed a new UPS to replace the old one i had. This has the same number of surge and battery backup outlets as the one before. The old one served me well for three plus years and i expect this one to do so as well.

    Basically to sum this item up, it is a fancy plug strip that has the amazing ability to power your devices long enough to power them down safely should the power go out and I love it!

    I have a piece of electrical equipment that I have to move around the house occasionally, and everytime I unplug it and then plug it back in I get an error message. Now I plug it into this battery back-up, so when I move it, it stays powered up. Works like a charm.

    This device works as advertised. One word of caution would be, the limitations on voltage. I have a portable AC unit plugged in, lamp and router. On a somewhat regular basis, it will triple breaker on the device, needing a reset. Beyond that, though, I am very satisfied.

    Second one of this model I have purchased in last 2 years. They work fine for a few years until they suddenly fail. We had a brief power failure. When the power restored, the non-battery supported side of the device was fried. It's intended purpose is to work under these conditions, but two years is what you get for this price.

    Living in N.C. by the shore I am used to power fluctuations. This little powerhouse has saved me more times than I can count. Easy set up, just remember to charge it the 1st time before usage.
