Let me start by saying I have an APC Smart-Ups 750 from 2004 that to this day is STILL running like a champ. I've replaced the batteries about 4 times in that time frame. This model looks, feels, and smells just like the old with a more modern front panel and cloud service port. It feels just as well constructed and in almost every way functions the same. The updated display lets you change certain settings and displays the current load and charge. The SmartConnect network port is a fantastic addition to this device. It connects to the APC SmartConnect cloud service and monitors your UPS at a simple and basic level. If it's online or on battery, estimated runtime, charge, temperature, firmware version, input/output voltage, load, when you should replace the battery, warranty date, and an event log. It will send you an email with the alert level you would like as well. This is REALLY nice feature out of the box without needing to add a management card, which they can get pretty expensive.

I'm in IT and have purchased 50-60 of these units in the last 3 years with no problems. No DOA's and non have failed yet. I find that 550VA is great for single workstations like Core2Duo with duel 19" LCD's.

This is a must have item no matter where you stand in the tech world. I had 2 power outages in the course of 1 day. Lost some of my data and a couple of files. I then decided that I have one of these already why not buy another. Turned around and bought 2 instead. I had another outage couple days after. This thing really does what it is suppose to. It shut down the computer and also gave the alert tone. To anyone who does not have this item......run to the store or order from Newegg or you will be sorry.

Great product. I forget it's there until the power goes out, and it gives me more than enough time to shut everything off. Been using it for a few years now and the batteries are still good. Better than the AP* brand we use at work.

This UPS was a great solution to support networking equipment (modem, router, switch) that I installed in my basement. It has lots of outlets and the size of the unit was perfect for mounting on the network wall panel.
