Ratio Four coffee machine in black, new in unopened box. I backed the Kickstarter for the Ratio Four in December 2023, received my unit directly from Ratio in November 2024, and have never opened or used the package or used the machine. Backed by a five-year warranty from Ratio. Photos of the machine in this listing are from Ratio Coffee's website.

The Ratio Four puts out between 5 and 20 ounces of coffee per batch, enough for one to two reasonably sized cups, or one big travel mug. Materials: BPA-free water tank, silicone water lines, handblown glass carafe, matte finish polymer base with reinforced metal internal structure, stainless steel.
