    REplacement for an older unit. It performed ok, the older one seemed a little more durable. In the summer months, we seem to get more spikes and such. This new unit shuts itself off more than the older one. I guess thats what it does, the equipment attached is safe and thats more important.

    I started buying CyberPower after several deceptions with the direct competence. As any CyberPower unit, it does the job perfectly but remember, the batteries, regardless of usage, do not last more than a year or year and a half. The good thing about this units is how easy is to replace the batteries and the cost is inexpensive (compared to the competence).
