This UPS provides the necessary power to my Internet Modem, Security Camera and Backup Harddrive. When there is either a power-surge or power failure this UPS device kicks in seamlessly. The beeps indicate exactly that it has been triggered and operating on its internal battery power. I would recommend this to anyone.
I use it to connect and protect, (of course) my 70" led tv. It is perfect, the lcd display with a dim adjust is an cool feature. The cable connection and the tel line connection included in this model, an excellent feature to protect it also. The 8 outlets for 8 devices, perfect. I use it in battery mode, when energy fail, to keep on my modem and a laptop working. The "voltage regulator" is, for me, the most important feature in a battery backup. The 60min and 180min running time on battery, depend of what devices you connect, very reasonable. I don't keep my tv on battery, only small devices if is necessary.
My company bought a dozen of these units. During several significant power outages, the Smart Pro held every unit to task. I knew I'd own one and have received the same results with my home computers.
