Great salt and pepper set! I love that it has a light that makes it easier to see how much is coming out. Very easy to use, easy to fill, nice selection of grind sizes. It is also nice that it has a base to hold it because there is a very small amount of salt that comes off the bottom so it keeps it from going on the counter while not in use - it's not leaking, just leftover residue from the grind you have just finished.

They’re nice… if they work…

Color: 2-Speed Rechargeable Set with Base

I ordered four of these grinders and two of them broke down while a third never started up. I am honestly disappointed in the failure rate of these otherwise nice grinders. If only one grinder in a two-pack failed, I would’ve just taken it on the chin and moved on. But three out of four total is unacceptable. I like the way they look, and the grind speed and settings are nice. But there’s a serious durability problem they need to fix.

Highly recommend!

Color: 2-Speed Rechargeable Set with Base

This electric mill set is great! The mills stay charged longer than I ever expected, and the operation is consistently very good. Since purchasing these four months ago, I’ve only recharged them once…and our family uses them nearly every day. Having the activator button on the top is the best…no accidental messes like the ones with activators on the side that can be inadvertently touched when grasping the mill. Having a stand to catch the small grind remnants also keeps your counters clean. They are a perfect height—large enough to hold significant product and small enough to not tip over. I also purchased a set for my parents, and they love them as well. Great product!

Sleek, Easy to Use, and Works Perfectly!

Color: Upgrade Silver, Size: Rechargeable

I absolutely love this electric salt and pepper grinder set! The stainless steel design looks modern and elegant on my kitchen counter. They’re super easy to use — just press the button, and you get a consistent grind every time. The adjustable coarseness feature works great for everything from fine salt to coarse pepper. The built-in light is a nice touch when seasoning food at the table or over the stove. Battery life is good, and refilling is simple. Excellent value and quality — highly recommend!
