You are right. Because it can guarantee your gadgets security to an extent. But I don't appreciate anyone to completely rely on it because sometimes the heavy voltage spike can break the surge protector itself. Our new PC got damaged when a lightning strike despite the fact that we had a surge protector. We haven't realized that surge protector wasn't working. It is true that surge protector shields the gadgets but it has a limit. When you get a surge protector ensure that it has an indicator to indicate whether it is working or not. Now we had a
surge protector brought from Barrie, with indicators. Even then, we unplug the gadgets from the sockets during the lightning.
