    Have had no problems so far. easy to set up. only thing I haven't figured out is why every so often it starts peeping for no reason. I shut it down and restart it and it's fine. doesn't happen often.

    I use a CPAP machine and when the power goes out, i cannot sleep. I bought this so i can sleep during power outages. This is the 2nd one i bought. the first one I bought i used for my computer. The only thing is once it turns on it will beep. Not sure if this one beeps or not since the power has not went out since i bought it.

    Great Product to help protect my PC and other electronics. I never had an issue with APC products so any trim level of protection should be fine. Just remember the more volts you buy the more time you will have on the battery.

    Has already come in handy during tropical storm. Power went off and on quickly a couple of times before going out for 3 hours. Battery backup kept my system running during the momentary outages and then provided me ample time to shut down when it went out for a long period of time.

    I bought my first APC power system in 1999 and it has worked very well for the last 15 years, In fact, it is still in use. I just needed a second one for a second room. APC is a great product and I have absolute peace of mind that my equipment, data, etc. is completely safe and secure. Highly recommended!

    We use APC units in our small office. They work well and used this one to replace an ancient one that the battery died. It works well for a single desktop setup. We recommend APC and never have any problems with them.

    This unit is very easy in install on your system and you can't beat APC for quality in UPS units. I put these on all systems in our office that use our accounting system to prevent those systems from instantly shutting down in a power surge and creating issues in the database.

    The previous battery backup that I bought from Best Buy did not work straight out of the box. So I returned it and bought this one on sale. I plugged it in and it is working fine .

    Battery Back-up and Surge Protector

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The battery back-up system has corrected a rebooting issue that I had with my Comcast router and security cameras. Prior to purchasing this unit, I had to manually restart my cameras after an outage. Connecting my router to the battery back-up unit has eliminated the need for manually rebooting after a loss of electricity or a Comcast temporary loss of service due to weather concerns, etc.

    I wish it wasn't so tall, so it could slide under the tv stand. But, other than that, I like it. It keep power flickers from making all my electronics reset themselves.

    This is a great product for a home network. I work out of my house and occasionally the power would go out briefly. This would cause me to lose my VPN connection and drop out of on line meetings. Since installing this UPS, I have been able to work straight thru any power blips.
