works
presumably the batteries will last a long time on a small load.Keeps power stable, and keeps the voltage it should be 100% of the time.Backup feature transitions nicely with no power cuts.

does what it should... sort of
I have not had to push the limits of time of this backup, but it seems fine. I tested it for a few minutes... I have tried and not been successful in getting the computer to "see" it so it can auto shut down the computer if I am not present during a power outage. Not sure what the problem is and don't have the time or interest in trying to pursue it via tech support. It hooks up via serial cable. I would think a modern appliance would use USB and be more reliable. I am running Win XP Pro.I do like it though because of the size (time it's supposed to run on battery power) for the relatively low price.

Power Surges
We have had 2 power surges, one was bad. We have two units, one on the computer, Printer etc. and one on the media center. Both worked as advertized.Very satisfied with the product.

Great quality, decent battery lifespan
I bought this unit in 2006 and it served me quite well for about 5 years. It is better than your average UPS because it detects abnormalities in the power and can "boost" or "buck" what is there without fully switching to battery mode. I have seen it do both. It also switches on/off fast enough that I don't even hear blips in my computer's sound. I also seem to remember it being marketed as producing sine waves, but I can't find that detail anywhere now.In about 2011, I noticed the battery life was getting quite short, and recently any slight power fluctuation would cause the entire unit to turn off completely. I pulled the batteries and tested them, and they won't hold a charge at all. They cost anywhere from $17 to $33, and the unit requires 2. I'm in the process of getting new batteries, and I expect the unit itself is still working fine.I suppose 5 years is fair for an AGM battery, but I also notice they are connected in series, so the UPS is working with 24V and can't individually float-charge the batteries. (I think the lifespan would be better with individual monitoring, or if the UPS ran off 12V internally off one larger battery.)
