Good buy
Color: Rechargeable Set with Base
I bought these for my son and his wife for Christmas this year. He loves them and uses them regularly. Super good looking, easy charging. Nice flow of ground salt and pepper. I have seen him using them while cooking so I asked what he thought.

Everyone Loves My Electric Salt & Pepper Grinder Set!
Color: Rechargeable Set with Base
Very nice looking grinder set. Rechargeable is the only way to go. They function with ease. I Love that I can easily adjust the size of the grind for both the salt & pepper. It is also nice to have a holder for them to keep counters clean. My family and friends have ask me to send them them the Amazon link so that they can purchase a set for themselves.

quick set up
Color: Rechargeable Set with Base
So far, 2 weeks, it was easy to fill, charged quickly, looks lovely, easy adjustment on the course to fine dial, great value, so far. and mush less clutter-y than the four different items I had to use to get both fine and course grands. Light weight and it appears to be built to last.
