Q: Never satisfied with traditional mills, I bought these because they had a unique design. I liked that they stick to the fridge but have found that means I occasionally have to wipe off pepper flakes. The small, rectangular holes make funneling refills difficult and messy. About a month into light use, the pepper mill gummed up and cleaning was a real chore. After about a year of moderate use, the pepper mill just wasn't grinding properly anymore. Cute but not very durable.
A:
Negative
