I've learned after a bit of playing that YOU CAN TURN OFF THE ANNOYING BEEPING NOISE! Use the included strange USB thing to hook it up to your computer, then use the free PowerAlert software from Tripp Lite's website. Switch the software into Business mode, then go over to the Action section. In the list of actions is "Set Audible Alarm". Set the value to 1 (even if it's already 1, overwrite it), then execute the command. After a second or two, the program will unfreeze, and it will be completely silent when it loses power from then on!

There's very little that needs explaining with this, really. Read the item description -- it does all of that, and it does it flawlessly in my experience. I've had absolutely no trouble using the thing, and the few power outages I've experienced were handled perfectly. (Even the one time it was accidentally unplugged.) The battery lasts my computer and monitor about 20 minutes.

The only small caveat I've noticed is that turning the power on or off causes the device to beep loudly. There may be a way to turn this off, but I've not found one, and it can be a bit of a pain when I'm trying to turn it off late at night! Of course, you really only need to turn it off if you're the type to unplug your computer at night (like me), so it may not be an issue for you.

I have had good luck with Tripp Lite products in the past, and this UPS is no different. I purchased it for several office computers and have had no issues.

They work as advertised and are usually slightly cheaper than APC. The device contains four ports with backup power and four with just a surge protector.

This is a nice feature and makes for a more flexible device. In a work environment though, it has caused issues. On more than one occasion, I have had people plug things like space heaters into the UPS side and blow the whole unit (not this model). One would hope that most people would know better.

Have you ever wondered whether UPS and surge protector companies will really pay out on the equipment insurance that they boast of in their advertising? Read on.

I had had my computer, monitor, and scanner plugged into a Tripp-Lite Internet350U UPS for over a year. I live in the country, and we have frequent power failures. When the power went off, the UPS battery immediately kicked in without a glitch. If the power came back on within a couple of minutes, it would return to the utility power and I would lose no work time. If the power stayed off, I had plenty of time to shut everything down without losing my work. The only complaint I would have is that the Tripp-Lite software was not the best, as it would not always recognize the UPS unit on boot up. A reboot would solve the problem, and the software is not really necessary anyway. The UPS will work fine without it.

Then, one night we had a thunderstorm around 2am. The computer, monitor, and scanner were plugged into the UPS as usual, but nothing was turned on. I know that the power must have gone off and come back on during the night because the clock on the kitchen range was blinking in the morning. When I went to turn the computer on, it was dead. Then I noticed that the UPS had apparently switched itself off because its lights were off. So, I switched it back on. I then tried to start the computer again, but it was still completely dead, no lights or fan. To make a long story short, what turned out to be the problem was a fried motherboard standby circuit. Since the computer was turned off but plugged into the Tripp-Lite UPS during an electrical storm, the obvious conclusion is that the UPS passed a surge through the computer's power supply to the ATX standby circuit.

I bought this to use with my Verizon FIOS router as the router is not protected from power issues. This unit is small and works well replacing a bulkier APC unit that failed on me. I suggest this for all home routers. I have a lot of experience with Battery Backups, both at home (I have them on every TV and computer) and previously as a IT Network Manager and would recommend this to everyone. The size and capacity are perfect for a router. Trust me on this one, getting one of these for a router will really save you headaches in the long run. I went with Tripp Lite as they have been around for a very long time, and to me, the lower priced APC units jut don't cut it anymore for me. AMAZON was the best deal for this compact ups when you consider shipping costs. I used Super Saving shipping and it shipped for free - the final price you pay is what matters. And I received it quite fast. No complaints. I bought it directly form AMAZON (as the seller) , it came fast, I installed it, and it is working fine.
