Rated 5 out of 5 by from Completely reliable, great product I've been working with this Back-up for a little while now, and my experience has been consistently excellent. As with other APC products I have owned, the craftsmanship is very high-quality and it gives me a high degree of confidence in the product.

Rated 5 out of 5 by from APC backs up their back ups! Had and issue with run time with the first unit I recieved. Called APC service and within 10 min I had a tracking # and p/u tag for the old one. Received the replacement in 4 days. What can I say...APC backs up their back ups! I have found that this product does what it specs out to do! Only issue I have is that the cooling fan is a bit noisy, but the good thing it doesn't stay on for long.

Rated 5 out of 5 by from Best equipment. I have been using APC products for 16 years. They have never let me down and even when they are outdated. Easy to in stall and manage. I wish more products where built with the same time, concern, and quality as APC.

Rated 5 out of 5 by from BK500BLK We buy APC products for their reliability. However they have changed from using right angle plug to straight plugs. Now I have more trouble with bad connections at the outlet than power failures because it is too easy to accidentally knock the plug out.

Rated 5 out of 5 by from Excellent UPS This is a nice compact unit. I like having the outlets on the back of the unit. One of my UPS units has the outlets on the top and they get dusty. I will replace it with one of these when the battery fails.

Rated 5 out of 5 by from Latest in a long line This is my 5th APC UPS. The last one stopped working after 10 years of dependable service. Nothing to do but replace it with something I know I can depend on.

Rated 5 out of 5 by from Trust No Other I have used APC Back-UPS for over 10 years with various home computers. The batteries do need to be changed at some point around 3-4 years. APC is up front about this. My current Back-UPS CS 500 sits next to my Dell Inspiron quad PC, filters line problems, self-tests, powers after commercial power is removed, and even shuts down my PC gracefully via supplied USP cable according to the params that I set. A PC application lets you initiate a test, review the test log, review power levels and more. It's well worth the price to protect an expensive PC like the one I use.

Rated 5 out of 5 by from Great Battery backup APC makes great products. We have 70 some of this battery backup. We use one on each one of our cash registers at our stores. We have had many for four years or more and have only had to replace a few batteries. They have protected our registers and kept them running in power outages. We have experienced no electrical problems with any of our registers while using these batteries. I recommend APC and use their devices on my electronics at home as well. APC is quality.

Rated 5 out of 5 by from Originally good, but batteries have short lives The first battery I received with the unit lasted nearly 2 years. However replacement batteries have been dying in months, the most recent one only two. I am changing brands, even though I purchased a spare backup battery.

Rated 5 out of 5 by from Largely positive review The unit is very sturdy and looks nice on my desk. I've also installed the PowerChute software and connected the unit via USB to my computer, which has a nice dashboard that allows me to monitor the system and change the configuration. My only criticism of the unit is that it's a bit loud -- it makes a constant humming sound. You don't really notice it if you have other audio going on, but in a quiet room it's definitely noticeable.
