Review (1/5): Don't waste your money!
The humidity was causing my salt to clump up so that it didn't flow at all, so I ordered this set based upon the reviews. What a disappointment!
I used one of these for my Himalayan pink salt, and the other for popcorn salt. Within a day or two both of them were caked up and useless.
Unfortunately I missed the return date for this junk. Keep looking for another product - this one in worthless.
