Customers are saying

Customers are positive about the 450VA Battery Back-Up System's long battery life, surge protection, and performance. Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    Was just going to buy a new surge protector but for $7 more I got the added protection of 30 minutes for file back-up in case of power outage. just seemed worth the extra $7. Do charge it before setting up new system as charging takes awhile.

    My Passport, was easy to set up and use right out of the box. But I don't need everything automatically backed up, just certain files. I know I can drag and drop but would have really preferred to have automatic back ups of these files. What is good is that it is easily used between desk top and laptop when I need to be away from home for more then 1 day.

    I purchased 2 of these units to provide surge protection/battery backup for our 2 PCs & perifaralls. We had a lighting strike that took out the house lights a few weeks ago. One unit performed as advertised while the other one took the hit but the battery backup portion failed to function. The following day everything was back to working correctly.
