    Does the job

    UPS that does the job; the only thing missing is an Ethernet or USB port to connect it to a NAS. Too bad.

    Good product with enough features to automate shutdown.

    Very good value for money,
    Well made,
    Connected to a NAS via USB, which acts as a UPS server, it can send a command to all computers on the network to shut down properly before the modem, NAS, etc. are turned off...
