The "title" or description of the grinder is a bit misleading. It is not a "salt and pepper grinder," "automatic mills" or "Salt Shakers." There is only one item, as pictured. It is not "electric." It is rechargeable with a USB connection, not a wall plug. I needed to buy an adapter in order to recharge it in my kitchen. Not a big deal and the adapter was very affordable. Just be aware. I've had it only a few days, but so far, so good. I love the "automatic" feature; just push the button located on the side to dispense freshly ground pepper - much easier than my manual grinder. It can be adjusted for coarse to fine grind by turning the knob on the bottom. A light illuminates on the bottom while grinding to better see how much pepper is being dispensed. I thought the light was an unnecessary feature; but after using it the first time, I'm sold! It's a handy feature to have. I'm very happy with this purchase!
