From Brewista: "The Smart Scale has been redesigned with a USB rechargeable Lithium-ion battery for longer life*. The Smart Scale II™ has the same water repellent nano-coating as the original, but is even more water resistant thanks to the completely sealed body and included silicone platform pad. It automatically tares, automatically times, and automatically shuts off depending upon which of the six available modes has been selected by the user. Perfect for pour over or espresso preparation."
