These units are guaranteed for life and the manual tells you to call for replacement whenever an indicator bulb indicates the protection circuitry is kaput

They are good about honoring their warranty

I had one lightening killed the phone protector they didnt make parts for any more so they sent the equivalent new model no charge

This model was cheaper even though it had additional coaxial and telephonenetwork jacks that we are not using

It works exactly as advertised turning off devices that drain power for no reason

I purchased this because i have a broadband internet provider and i have lost two routers to power surges

I connected this two hours prior to a storm passing through the area and i lost internet service

The provider called and said that they had to replace the outside equipment due to a lightning strike but my router is ok
