Ratio Coffee 5 star review on 18th November 2025

“I can't review this machine but as far as service from the company, I would call it poor. They do not offer an exchange. In order to exchange the coffee maker for another color, I had to reorder (which means I've paid for 2 machines at this point), and do a return. The rate at which the company responds is very slow 2-4 days for every email sent. They do send an automated message in the meantime. I've been waiting for a return label for shipping (costing me $26.00) because apparently, everyone is out of the office for the rest of the week (I called on Thursday). I don't understand why they didn't automatically send me a return label through email when they realized I was returning the white machine and purchasing the black machine. Then they could have deducted the shipping costs from my return. Instead, 5 emails later, and I'm still waiting for a return label. I've got over $700 into this, and I'm still waiting for a machine to be delivered to me, 2 wks later.”

“This machine makes a fantastic cup of coffee. I love how hot the coffee comes out, and the smooth flavor.”

“We were so excited for this purchase and it honestly fell a bit flat. This is a premium product, or so it says, and we received a defective carafe and a damaged package upon arrival. We called customer service to have this taken care of and the first response was to try to pull off the plastic ourselves. This not only will not work, it also is not the answer that we were hoping for considering we paid $400 for this item and it arrived damaged. We are currently still waiting for a replacement. The coffee maker itself makes nice coffee but the customer service has not impressed and is making us consider the electric chemex instead.”

Hi Allaire, thank you for sharing your feedback. We’re so sorry again about the carafe arriving defective and for the rocky start with service. I’m glad to share that your replacement has now arrived, and we hope it helps you enjoy your Ratio even more!

“This is a replacement carafe and the lid doesn’t have a tight fit like the original did. Disappointed in that change.”

Hi Stacey! Thanks for the review; if you'd like we can send you a brand new series 1 thermal carafe at no charge to you. Just let us know with an email to hello@ratiocoffee.com and cc mark@ratiocoffee.com Even though series 2 doesn't seal 100% it holds the coffee temp very high for over 2 hours (and reviews from 3rd party sources confirm this) so we decided to proceed with that design for its simplicity. Thanks very much!

“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.”

“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.”
