Did you know that this is bad news for your electronic investments and potentially your home?
Electrical surges will decrease the life of your costly electronics and a strong enough surge can melt the internal microchips of a device, destroying it with just one hit. These occurrences are irreversible, leaving the product un-repairable. Most manufactures will not replace an item that is damaged by an electrical surge. Electrical surges cause heating of wires, which can melt and result in a serious house fire. Protect you family and your investment with the new SurgeSentinel™, the Whole House Surge Suppressor.

Your home can be protected from power-related disruptions with one easy installation of the SurgeSentinel.
