    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.

    Once again, this product is just what I need! Replacing the old one was simple, and the fact that I could recycle the old one so easily was wonderful! Thank you!

    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.

    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.

    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.

    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.

    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 They have never let me down and even when they are outdated.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.

    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.

    Asked on 06.25.2011

    I am looking to buy the BK500BLK for use with a DVR. I am trying to avoid the power disruption during an outage that shuts down the DVR. A shut down requires a reboot by the supplier. Will this product provide continuos flow of electricty until utility power resumes ? It only draws 26 amps.
