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.

    bought a 650 which did not work, got a 450 which is working fine Had helpful persons when we were seeking one out and when we returned the first one and our G.Squad people have all been wonderful and good at explaining everything. Thanks! Ryan Dewey was great when we were trying to get connected again - he goes above and beyond for a clients service!

    A little more expensive than I thought; it charged in the specified time. So far, no problems.
