Works well.
Color: 2-Speed Rechargeable Set with Base
Close to 5 stars. Only minor complaint is somewhat shorter battery life then expected. But since it is rechargeable, not a big deal. Like the adjustable grinder and the clear container so you can see how much it has.

Great salt and pepper set!
Color: 2-Speed Rechargeable Set with Base
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.
