Query: It was great while it lasted.

We bought one pepper mill and liked it so much we bought another one. They were easy to use and did a great job. I particularly liked the ability to adjust the coarseness of the grind. The only problem at first was that the bottom would not stay on, which meant they wouldn't operate; we sort of solved that with some masking tape inside to add friction BUT THEN...after about 4 months they each broke - neither one will grind pepper (or salt). Unfortunately the "return window" was expired so we're out about $60 for these mills. Very disappointed.
