"perfect gift"
given as a gift to a family that entertains a lot and needed the salt grinder. This made a perfect gift and works great..

"Poor durability and hard to fill"
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.

"waste of money"
hard to squeeze, hard to fill, hard to get more than a pinch of spice. there is a miniature hole to get salt and peppercorns in the units, they spill everywhere and don't hold much so you're always filling them. The handles are small and hard to hold. You have to squeeze them at least 30 times to get a decent amount of spice out.

"Not for the serious minded.."
Perhaps the larger model works well. This smaller magnetic set is tragic. The only upside is that if you're working on your grip strength, these will probably help. To get a useable amount of pepper, you'll have to squeeze 15-20 times. They feel cheap and destined for a quick trip to the trash can. Stick with a tried and true twist grinder.

"Nice for the price..."
These are very good for the price. The handles do feel a little 'cheap' to the touch, but work exactly as designed. Simply designed, and the attached magnets make these a fantastic space saver, I placed mine on the metal overhang above my stove.
