Switch-over from mains to reserve power is too slow. My device that needs power is switched off and has to reboot after the reserve power is connected (TV Digital Satellite Decoder). Changeover is not immediate. It does not serve my purpose. It would be ok for something that does not need to be continuously powered. I am disappointed.
