Excerpt: I use this in my video rig to allow me to power down my equipment safely in a power outage situation. I had a power outage a few weeks back and my SD card based camera file footage was corrupted due to the power loss and camera not being shut down properly.
Summary: For lower power applications, such as an inkjet printer, network switch, even a router this is a good product. But remember it is very basic, and is not sine wave, so it should never be used with computers and other very expensive electronics.
Pros: I recently bought a Brother MFC here at Newegg, and needed a power protection for it. After debating between brands and capacities, as well as looking over some regular surge protectors, I decided on this unit. It's TINY. Literally it's not much larger than a house brick. It is also very light.
Cons: Not Line Interactive, no digital readout, high cost per watt rating, not sine wave.
Summary: make sure you do your power calculations and get the right sized ups. people who don't like this either rank it for low ups time or fails when switched off power. both are due to failure to compute their power requirements and run time requirements.
Pros: smaller than expected. compact design. no annoying beeps when power goes out after 1st button press to acknowledge alert unlike others that make you do it often. Great for router, PoE switch for the home runs in my house closet. Wall mountable.
Cons: none that I can find. its sized for what I need.
