Using on my tv, directv, roku, and sound system with no problems. The power here flickers on and off a lot and this unit keeps everything on with no problems.

I have used several APC UPS before and this one continues the high quality performance and ease of use. the Power-chute software makes tracking power quality simple.

This is a great item that helps me to protect my computers and any other important devices I have when the power goes out and since I live in Florida that's more often than I'd like!

Great basic surge protector and back up power supply. Was on sale at my local store and I needed one. Only drawback is my child loves to hit the button which deactivates the power to the devices.

Needed a battery backup system for a small computer setup and this did the trick. Also, the router is a dependable model I've been using for quite a while.

The point of a UPS is to protect your equipment for power fluxes and lightning strikes. Both have happened in the month I had this product and it worked as advertised.

I have had this UPS since the beginning of the year and couldn't be happier. I love it when you buy something, plug it in and it just works. This is one of those products.

I bought two of these for my mother-in-law, 94 and insists on living alone. We know that her telephone and life-line service will have power if she loses power. We had one 15 minute test: no lights but she could call us. All of us feel better now.

Bought this when we were having many thunderstorms. We were having brief blackouts, but the modem and router would reset, resulting in about 2 minutes of no internet. This solved the problem. Also, surge protection is a good idea in general.

Recommend this product, definitely over the other brands! The others require you to plug in then gradually plug in the other equipment, APC will work fine no matter what!
