Mediocre salt and pepper grinders
Color: Upgrade Silver, Size: Rechargeable
Pros: They do work, and they are rechargeable. Cons: the motors run really slow, capacity is low, The charging tray you have to empty frequentlyto reduce buildup underneath the salt and pepper grinders.

Sturdy Workhorse
Color: color AA
This is my second time buying this pepper grinder. I first bought it 4 years ago. It is an attractive and sturdy pepper grinder, made of thick glass and metal top. Very easy to fill and did the work as intended for 4 years, and we are heavy pepperers. Then my son knocked it off the counter and it broke. But I can't blame the product for that, it admits right up front to being made of glass.

Great pepper shaker
Color: color AA
I really like this pepper shaker. It works great for me. It's easy to feel and the grind is good. I can get the different sizes of grinds. I like with my pepper and it's easy to clean. All I do is have to wipe the bottom down and make sure it doesn't get all caked up with it. The residue from peppercorns
