Performance
The K-Express brews quickly and consistently. The Strong Brew button noticeably enhances the flavor of dark roasts and medium blends by slowing extraction for a richer taste, and the 42-ounce reservoir means you can brew several cups before refilling. Operation is genuinely one-touch — insert a pod, choose a size, press brew — and cleanup is limited to occasionally emptying the drip tray and descaling periodically for optimal performance.
