I put the parts through the wash to sterilize them before using them. I think this introduced moisture into the grinding unit, which initially affected the grinding so that both the pepper and salt were coming out 'chunky'. I disassembled them and let them thoroughly dry. They are working great now after using them a few times.

A Perfect Gift For Someone Who is Tough To Buy For

Size: 5.3 Inches - 2 Packs with Holder

Very attractive looks and quality build. Most importantly the salt grinder will take sea salt down to powder for popcorn (a make-or-break feature in my house). It doesn't take up much room in the cabinet when stored and very easy to fill. We're just delighted with the value for the money. Any time you are stuck with what to get someone for a birthday, xmas, what ever; you can't go wrong with this Salt & Pepper Grinder Set.

It works but it's not high quality

Size: 5.3 Inches - 1 Pack

Grinder works well except the silver part came loose after using it a couple of times now we have to hold the top part really tight to use it probably should have returned it but it still works

Good Salt Grinder

Size: 5.3 Inches - 1 Pack

Bought this for the pink salt. It crushes it nicely and is easy to fill. The crushing didn't change the taste and this holds a considerable amount of sale. It's a great value for the money and would make a terrific gift.
