    Used this for a customer's video surveillance system installation. Supported the DVR, router and modem so system would remain operational during brief power outages. Wall mounted it to save space. Easy to set up and use, dependable (so far). Recommended!

    The UPS only provides power for a PC and monitor for a few minutes, but for most people that's enough to manage brief power outages. A solid product for the price.
