Query: Salt mill zero stars would have my first choice

I purchased both the salt and pepper mill as a gift for my husband. The pepper mill works great but after a very short amount of time the salt mill stopped working properly. I have changed the batteries several times but it never seems to work right. Had I purchased it in person I would have returned it already. I'm online now to find out if I can exchange it.
