“Was expecting a better tasting cup of coffee. Also, I don’t understand why the lid doesn’t close completely. In the closed position if you tip it, it will pour, which makes it spill risk when traveling. For $350 a little disappointed.”

“While I am happy with the coffee machine itself, I'm not satisfied with the carafe. It simply does not keep the coffee hot. Good for 15 minutes or so, then coffee is undrinkable. Honestly wish I had not made this purchase. Rated 2.”

Our carafe is designed to keep your coffee hot longer, so we really appreciate you sharing your feedback. If you’re up for it, we’d love to help troubleshoot and see if there’s a way to improve things. Please email us at hello@ratiocoffee.com—we want to make sure you’re loving the full experience!

“Did you know they used to make the water tank out of glass? Could have been plastic free… And is the tank supposed to hold 40 or 44 ounces of water? The fill line is 44 ounces which will fill the stubby little thermal carafe to just millimeters from spilling over (pro-tip: 42 ounces is the middle of the full circle – 1190 grams). Speaking of, the thermal carafe is probably the worst part of this set-up. Too top heavy, prone to dribbling, have to invert it completely to get those last drops out, and make sure you have the pour spout/handle screwed on very well. Oh, and cleaning it? Hope you have tiny hands to get in there. Alas, as I near the end of my return period, I decided to keep it as I figured out how to make more acceptable cup of coffee for my wife than the Moccamaster we had for 9 years which recently tried to melt a kitchen outlet.”

“It’s way way too heavy. It doesn’t feel good on the wrists. Also, it definitely doesn’t keep coffee warm enough for the price. Almost better off using the regular glass one.”

“Great customer service. Just wish the product was a little more trustworthy for the price point. Several family members have owned the ratio and mine was the last one working. Love the idea and plastic free components are my biggest vice so love the ratio for that but wish it was just more trustworthy”

“The machine makes good coffee but it is unbelievable to me that a coffee maker this expensive would have such a terrible carafe when it comes to pouring. How do you get it this wrong? Does not pour smoothly at all and can make a mess. Not happy about it. 3 stars”

“Disappointed that cold water tank is plastic. Is that a recent change? Seems misleading, especially if that piece used to be glass. At that point what is the different between the 8 and 6?”
