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.
