If you need a basic UPS that just gets the job done this is it. It is not expensive and does not do much beyond power devices when the power goes out. I use one to power my home server, router modem and phone system when the power goes out.

Needed something for the router since my phone is IP based. Lost power last week for 40 minutes. Our IP (Magic Jack) phone worked, I could use my wi fi on the laptop also. Works for me.

Have had this product for a few months and no issues yet. Will have to see how the product lasts in the long run though. A bit expensive overall.

We wanted a couple of UPS systems that were small enough to put under an individual's desk, but would still provide backup for monitors connected to a laptop when a power outage occurred. These were perfect sized and have worked great.

I have trusted APC for many years. I use their UPS;s primarily for electronics where not losing settings is important--recorders for TV programs, cable boxes, and such. This works well. In addition, it lets you know when you have reached a level approaching an overload on a GFI circuit by beeping. There is no problem setting it up by connecting the battery.

I've used this UPS for about a month to keep my Internet radio station (ridgecreek.caster.fm) running 24/7. Of course, the real test will be if/when it is ever needed. But, I have used APC UPSs before, and I have every confidence that it will do fine.

This is the third one I have purchased to protect my equipment. I use it for more than my computer equipment. I have my phone and iPad protected with it. Works great when the power goes out. Great item to charge a cellphone if the power goes out.
