Query: Fun to watch, but don't think it works

I bought one of these from a different store a couple years ago. The first year I thought it may have been working. This year I forgot to put it up until I noticed tunnel action in my 100s.f. garden... and about 1/4 of my 75 garlic plants gone, and 7 out of 8 kale plants gone with tunnels under them. So I put the windmill back up, lubed the bearings and let it spin in our near constant wind. Like one other reviewer said, I also have tunnels right up to the pipe it is mounted on, and everywhere else. I'm guessing the pocket gophers or whatever I have are also responsible for my lack of sunchokes and probably the potatoes as well.It makes a nice yard ornament, but it doesn't keep the tunneling critters from eating your food before you can! I guess I'll have to try raised beds with a heavy wire mesh on the bottom next year if I really want to be more self-sufficient with food production.
