[Q]: I only used it a couple of times, a tiny bit of water leaked into the battery compartment and now it is rusted and won't turn on.
[A]: Negative


[Q]: Comfortable right out of the box. Well made. Durable. Can't vouch for the waterproofing of them, as I have learned many moons ago.....no shoes are waterproof. I refuse to test them, once you do...they never seem to be the same.
[A]: Positive


[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
