Query: Quit working after one month

I bought this mill from a reputable store and was impressed with the volume of grinding that it did. However,it would not adjust to the other settings. After a month or so it quit grinding pepper all together. I have sent it to the company for repair or replacement. We'll see if the lifetime guarantee is for real.UPDATE: The guarantee is as advertised. I have received either an identical mill or my old one repaired as good as new. William Bounds does back their products.
