Worked great so far. Shortly after installing in my home we had storms and the electricity went off for a short time. Unite protected all the computers connected to it and other items.

Got this for a PC at work that has a 4 channel security DVR PCI card in it. We have a backup generator there so it only needs to hold up this PC for a few seconds and so far no issues.

We held off purchasing a UPS for a work station. After a power failure we decided it was cheap insurance for the next power issue. Very happy with APC product line. One word...Reliable!

Best Battery Backup option

As a tech living in Miami I have the unfortunate need to require Battery Backup systems for my clients. I say unfortunate because of the violent thunderstorms that can plague our area during the rainy season. Having said that, due to those circumstances I see can better judge how well these APC units react to adverse power situations. This brand is always my number one choice for clients. They hold up very well to multiple power loss situations and they rarely need immediate replacing. Keep in mind that the higher the VA rating, the longer your device will stay powered during a power outage. I even use the larger models to protect my Flat Screen TV's.

The APC battery back up was recommended by my Computer Guy. It was put to the test over the past few days when the power went out because of the bad storms in the area. Works for me!

Needed this as in FL lightning is abundant. I had to replace power supply and mother board due to a power hit. Surge protector doesn't cut it. This UPS has performed perfectly in the storms...

I have used these for years to support our restaurant computer system. Time flies but they seem to last 4-5 years. I've used several different brands and APC is solid. I have had no problems.

We have frequent power blips. This backup keeps the modem and other electronics from experiencing these blips. Works great. Only complaint is the outlets are tight to plug into.

Best Buy offered the best price for the product. The battery in the last one I had lasted for 10+ years. Found it was a better deal to buy the whole thing rather than replace the battery.

This is for everyday use for a computer PC and monitor. It does exactly what it should, and the researched battery life is well worth the price. Definitely will buy more.

I bought this UPS to replace a 12 yr old unit. I use it in my spare bedroom for the TV and Dish box. Set-up only took a couple of minutes, and there are extra outlets for future use.

This is my 4th one of these devices and these are great for when the power goes out and gives you time to shut down things gracefully without worrying about messing up a hard drive.

I needed something to assure me that when I had a power surge it would not destroy my TV, DVD and cable box. This has worked great and I would highly recommend it.
