Gadgets to keep woodpeckers away

I wonder if any of you came up with an effective gizmo that deters woodpeckers from cedar siding of a house, in my case a tall chimney. I've tried shiny streamers that were effective till they were thorn away by the first wind storm and I am now too old to climb ladders to replace them after every storm. I also tried a fake owl near the chimney, but that didn't fool those peckers for very long. I've seen some electronic gizmos online, but I'd like to hear from somebody who has actually tried them and was satisfied with the result.
