We got the SECO whole house system for a one time cost of $349. They clearly state that it will not protect you from a direct lightning strike but will protect all large appliances from voltage surges from nearby strikes or anything causing voltage fluctuations. It is recommended to put surge protection on garage door openers which are ultra sensitive to any electrical anamoly. This is but one line of protection but it is a big one.
Properly grounding gas lines is also a critical issue.
IMHO, there is a good demand for the service..... so happy customers would indicate to me the validity of installation.
