Well, not mine but my cousin's. Years ago her husband told her to keep this and don't lose it. But now they can't remember why. LOL. For some unknown reason, she thinks it might have something to do with the radiators in an older home rental unit they have. Can anyone help identify what this is and what it's used for? The base is a suction cup. You all are so good on Bobski's items I thought you could identify this item.
