Sorry to say, I've used them and had them eat themselves. They just die mysteriously and let out lots of smoke when they do.

Interesting. So far the feedback sounds overwhelmingly negative. Heard some good points on Emerson (I'm assuming Liebert?). We've had much better luck overall with them, although a couple of incidents where they don't care to come back online after they were drained.
We largely use the UPS to survive power glitches without dropping the network for switch reboot times, we're not after long runs. As such, the occasional extended outages drain the UPS'es and there are always the percentage of them that do not come back online and require manual intervention.
We were formerly a big TrippLite user, but they seem to be incredibly fault-intolerant with regard to the scenario above (coming back online after draining), and to a lesser degree, going offline after a power glitch.
Never used an Eaton that I'm aware of however.
Would be interested in other recommendations for remote / IDF / MDF environment UPS systems to just "keep the stack up" over power glitches.
I do have much larger Eaton units like the 9355 that haven't given me anything to complain about yet. But they're of a wholly different classes and I don't really expect one to represent the other. The 9130 that exploded was my first foray into their smaller side, destined to be a telco room aux unit and replace an APC SmartUPS. ~Seth
