Overview: One-Hand Operation – Free your other hand! Not like traditional grinders, you can add fresh pink Himalayan salt and color peppercorns when you are cooking or BBQ. Electric grinders make it much easier than doing it by hand cranking! Gravity Function – Great for olders, children and cooking lovers. Refill – The clear glass jar can tell when to refill. The stainless steel top easily screws off and the wide mouth on the jar makes that chore a breeze. USB Rechargeable – No need to buy batteries, save money. Customers' experience tells us “USB charging is so much better than changing batteries”. LED Light – When the electric grinder starts up, the LEDs turn on synchronously to realize how much salt/pepper is being poured.
