understand the tradeoffs

This unit gives you sine wave output with no frills at an attractive price.
Be aware of the limitations of this new model at its price point. This is not a desktop product, so don't expect extras like ethernet or coax surge protection. It is less capable than some other APC UPSs with equivalent VA ratings; for example, the SMC1000 is rated for 600 watts, vs. 700 for the SMT1000. It has a 2-year warranty, rather than the 3 year warranty carried by most recent APC products.
Most importantly, this unit uses the new "Microlink" protocol, and does not have an expansion slot for adding a UPSLink interface. This means it will never be possible to fully interact with this unit using open source software, such as NUT or apcupsd; you can only get the most basic information out of it, such as line power up or down. Neither NUT nor apcupsd will be able to query it for load, output voltage, recent events, or many other things.
If these limitations don't concern you, it's a good value, and is the lowest-priced APC UPS with sine wave output. It's perfect for protecting the availability of a small server.
I noted that another reviewer complained of noise, but mine is nearly silent except when operating on backup power.

Good product, good value
By Tog
The "SMC" line differers from APC's "SMT" line mainly in that you can't plug in their $220 Network Management Card. If you will need that level of sophistication, by all means look at the APC Smart-UPS SMT1500 1500VA 120V LCD UPS System instead.
(Note that APC's older "SC" line that the "SMC" line has now replaced delivered an inferior type of power that only vaguely approximated, through a series of stair-steps, the smooth curves of normal power. The new SMCs deliver the same smooth sine-wave power as the SMTs, erasing the critical difference between the two.)
I've been buying APC sine-wave UPSes for around a decade now and have been very happy. They are smart looking and work well.

This is a good UPS from a size, capacity, and functionality standpoint, and if you're going to put it in a typical semi-noisy office environment or a server closet, then it's great. But if you have a very quiet office, you'll hear a constant low buzz from the unit. I don't mean the inverter buzz while it's on battery (that's expected) or the buzz when it's recharging after an outage (also expected). But a constant low buzz while it's just sitting there stable. It's on the floor about 5 ft away from my ears, and it's annoying. Maybe I'll get used to it after a while and my ears will notch out the noise, but after a week of listening to it, I'm kinda disappointed. EDIT: Either I'm getting used to it or it's quieting down. It's noisiest when the line voltage is below 120 and the unit is boosting it. Acceptable!
