Fair price for a good product
Size: 5.3 Inches - 2 Packs, Size: 5.3 Inches - 2 Packs
Good value for the money. Seems to work well I like the small collapsible funnel, but it doesn’t work to fill the container.

Great purchase!
Size: 5.3 Inches - 2 Packs with Holder
This set is lovely. Very s9harp looking contemporary design, just the scaled down size I need for the counter. And they function well too. Easy to adjust the grind.

Cheap Chinese crap do not buy!
Size: 5.3 Inches - 1 Pack
Outer stainless steel, plastic ring separates from the actual grinder housing and it does not work with a damn. It’s an absolute piece of crap that I’m returning..

Sleek and mostly simple assembly and use
Size: 7.5 Inches - 2 Packs
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.
