Eaton 9130 UPS feedback

Does anyone use Eaton 9130 series UPS for anything? I'm curious how they've worked out for you. I bought a 700VA model to give it a whirl versus the traditional APC since the Eaton is an online type with static bypass and also does some high efficiency thing where it normally stays on bypass, but the first thing it did on the bench was have the inverter/rectifier or bypass section catch on fire and destroy itself. ~Seth
