    Once again, Best Buy exceeds my expectations because we had been in search of this exact type of back-up power supply system. Thank you so much Best Buy!

    I purchased this UPS for my Internet router and hard drive for my security cameras as a power backup when away from home. I never lost power to any of these and had access to all my security cameras at any time. I recommend this ups for any item you don't want to lose power to.

    I plugged my internet/cable router into this. Protects from the occasional/short power interruptions that would normally cause a reset. If you purchase one, it does take a few hours to charge up before putting into use.

    I like the engineering applied on this compact system, that gives a sound alarm whenever you have a power failure and that it is using battery power for everything you have connected to it.

    Battery back ups not only help if there is a power outage, but they also protect you system from power spikes and brownouts. This one is a great choice.

    Bought this to keep the DVR from losing its programing every time the power went out. Replaced the same model with this new purchase. Old one lasted about 3 years. Replacement batter cost almost as much as the whole thing and had to be ordered so it is easier just to buy a new one.

    We had workmen in the house using a tile cutting wet saw. It saved my tv by shutting it off when that saw overloaded the circuit. This product really works.

    Haven't really had an opportunity to see how long the battery back up will last. We have had a problem with solid state hard drives crashing and hope that this will solve that issue. Will review later if this doesn't resolve the problems we have been having.

    Printer/s and phone sets and anything else that work with your computer need surge and power back up for when things go wrong. Well worth the price the first time it does it"s job.
