This is the 2nd one I've bought, the 1st one worked and saved me thousands when it knocked the surge unit out instead of all my electronics I had plugged into it.

I have brought this product several years ago and it worked great. We definitely received our moneys worth.

This is the an excellent back up battery. I have purchased this same brand previously and it has saved me a number of times when the electricity goes out in my townhouse.

Initially, i just got a regular surge protector for my new IMac 5K. For an extra $35, i brought the surge protector back and exchanged it for the battery backup which isn't even the cheapest model they have. Works great. Don't have to worry about a power outage, surge, brownout or anything messing up my computer in the electricity sense. It even integrates with my IMac that it realizes when theres no power and will turn itself off as i set it to. Integrates with Apple OS X so that i can set it to turn itself off if I'm not home and i dont have to worry about physically being there to manually shut my computer down. Its pretty much fully automated, as long as you go into system preferences>energy saver and set it from there. No 3rd party software to install, which is great since its literally integrated into my mac's operating system. this is a can't go wrong item. For a relatively cheap amount of money, not only do i have surge protection but i have a battery that will keep my computer going and possibly keep it from being damaged by a black or brown-out. Love the integration with apple's operating system.

This is my third battery backup. Couldn't ask for more. They give me enough time to save any work in progress during power failures and provide surge protection when the power is on. Unit also provides a convenient way to plug all components into one central unit.
