Anne,

I have used nothing but APC units for years and years.  Can't begin to recall 
how many I have had and all but one reconditioned model have worked 
beautifully.  I have never used the software to shut the units down so I can't 
say how well it works, I would imagine slick other than software that ask if 
you want to "save" the changes, or Safari that ask if you really want to close 
all the tabs.  Possibly APC writes code to override those questions and shuts 
it down anyway, I would like to know myself.

One thing.  When the unit gets low, really low and it continues to warn you it 
would be best if you paid attention and replaced it.  I didn't and one unit 
actually began omitting a burning smell, VERY strong so I don't know if I was 
about to have a meltdown or what.  Another time I kept having a fault breaker 
trip and I could not figure out why.  Time and again, finally I replaced the 
APC unit that had been flashing and omitting their death sound and the tripping 
of the breaker stopped.
