Example Sentences

It also offers a pressure indicator that’s more visible when engaged, and a steam-release button separate from the float valve so there’s less of a chance of mild steam burns when you’re quickly releasing pressure from the pot. And the Ultra cooks foods as quickly and reliably as the Duo, with some extra functions like custom temperature control and an altitude-adjust function.”
