Its amazing how many brown outs people get and you'd only realize it with a UPS or surge protectors. I have 3 in my office, 1 main one and then 2 that connect into the first one (and all my devices branch off the 2 UPS'). This way I have a secondary point of failure in case one UPS fails. And my office building is surge protected in every outlet, so with all this, I'm pretty sure its safe
