Sold the cows and don't need this anymore. Will turn according to the direction of the wind and shield the rubber tub and the mineral in it. Keeps the rain and snow out as well for the most part. It works good but don't need it now.
Don't worry about the date on the pictures--it changes every time I put new batteries in and I don't know how to change it back.
