Defective coarseness adjuster
Color: Tall Set - Black White
These salt and pepper shakers are ok. According to the description of the product, you should be able to adjust the coarseness of the salt and pepper added to them, but that was not my case. The coarseness adjuster on the set I received is set to one position and there is no way of changing it. The grinders work well, but if you are looking to adjust the coarseness of your salt and/or pepper look for another grinder set.

Great shakers with convenient dock
Color: Silver, Size: Rechargeable
These are very nice. Work very well. My only complaint is right where I pick them up is the button to turn them in so I’m always accidentally salting the counters lol. Easy to refill. We like the lights. I love that they have a charging dock so they are always fully charged. Very happy with them.

You don’t have to shake it. I love it
Color: Silver, Size: Rechargeable
Different settings from fine to course. It has a light around the bottom where you can see how much you’re using. It stays charged for a while. The quality is great. Well made.

Beautiful set
Color: Silver, Size: Rechargeable
So far love this set. It was a gift for my boyfriend and he loves it. The look is perfect, and so far functions as expected. Also the charge has lasted for months so far.
