IMHO, these are effective for the close in strikes, they will do nothing for a direct strike. Also, these will not protect EXTERNAL wiring, landscape lights, pool controls, and other wiring that goes outside the house.

I hadn't thought about EXTERNAL wiring. That's a great point. If the ground lightening is picked up by that wiring, the surge protector will not help. Nothing is 100%. I would think lightning striking in your property is far less likely than it striking somewhere along the electrical grid serving your house. I wonder if the power co can tell the difference and not pay on warranty claims for this situation?
One thing I know that works is unplugging things. I am a snowbird. When I leave for the season, I unplug everything I can, including all appliances. So, nothing is 100%, you have to have risk mitigation strategies.
