This product fully meets my expectations in case of power outage or power surge for: PC, Box, Telephone, Printers, Screen, HP ... Also it has taken two "eco" that cuts power chic accessories above as soon as the PC is off. Note that the software installation is not obvious to everyman. Main flaw as many of connection accessories, you can not connect 8 transformers (Dimensions of them too large relative to the distance between the PC station)
