“There’s a lot of condensation from the tank. And wis the water was hotter. Feel like my coffee is just slightly above warm.”

“Produces amazing coffee. I appreciate that no plastic ever touches the water. However, the machine feels extremely cheap. Lightweight plastic body, no handle on the brew basket, lightweight wood stained walnut that actively detracts from a premium feel. The thermal carafe feels like it could survive a nuclear war. I wish the brewer itself was constructed with the same level of thought and concern. I’m not going to return it because it does make a good pot of coffee, but I expected much much more from a $700 drip brewer and I would never recommend the purchase to anyone. I’m leaving a 3 star because it does what it says and produces good coffee, but I regret the purchase at this price point.”

“I purchase this dripper for my Ratio 6 S2. It function well with mixed results. We use If you care 8-12 cup basket filters and pour over grind size for the beans. Normally, my wife and I brew 6 cups but, for the holidays our kids came home so we made the maximum 8 cups. When brewing the max, the dripper stalled causing the dripper to overflow all over the counter; not a great start to Christmas morning. It does not happen when less than 6 cups is brewed. Secondly, a handle should be added because the dripper exterior is still hot after the ready cycle ends making it necessary to wear oven gloves to remove it from the carafe and it is too large to hold with one hand. To end, the dripper is high quality and appears to be engineered to last a long timeb; I wish it would make the full 8 cups.”

Hello! thanks for the input - we can assist you to be able to brew a full 8 cup dose! We find there are usually two causes to overflow: grind is too fine, or the paper filters are thin and stopping up the flow of coffee at the bottom of the filter. We will email you some further details as we have thousands of people brewing full batches with this filter without any issue. Stand by!

“New shower head represents some improvement over original design, i.e., improved extraction, but it addresses only one of several deficiencies present in the Ratio 4, e.g., location of the START button (erroneous location cannot be mitigated by changing sensitivity) and difficult-to-clean basket (plastic material and large fins; stainless steel, please!).”

“The product page for the Eight Series 2 makes no mention of the aluminum boiler. This omission was shown on a different page, which applies to all their coffee makers. I returned the unit unopened as I will never make coffee that heats the water in aluminum.”

“As you can see in the picture, the stainless steel is surrounded by a ring of plastic that in my usage is prone to peeling and breaking. So if you’re looking for a plastic-free experience to avoid microplastics in your drink - look elsewhere. There are fully stainless steel filters out there on other shops.”

“I like this carafe and dripper and find it very handsome. but we all wonder why on earth the metal handle and rim are so incredibly heavy? Also the rubber stopper needs tweaking as one has to let a bit of air in at the back of the stopper to get a decent pour. These are significant problems for houseguests who treat the setup gingerly. Too bad, but it’s good to look at first thing in the morning.”

“I have never spent this much on a coffee machine so I was expecting a little more perfection in the details. For me the coffee brewed is excellent. What upset me was I was using Ratio paper filters and 85 percent of the time the water backed up in the filter and took me to lift the hot paper filter up for it to flow. Next if I don’t perfectly align the glass pot I find water under the glass pot when I remove it to pour coffee. It does not leak the water coming out hits the rubber ring. Steam condensation forms on the outside of where the water comes out and you have to wipe it off. It might be me and maybe I am too picky but want to say again the coffee is great.”

“Hells but doesn’t keep the coffee as warm that long”

“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!

“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.”

“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.”

“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”

“Love the Ratio 8, elegant and easy to use, very beautiful in the kitchen, 5 stars. Not a fan of the thermal carafe, 1.5 stars. It is uncomfortably heavy and hard to pour until empty (has to be tilted more than 90°. When full of coffee, it weighs over 4 and half pounds! This makes it unwieldy in your hand, like a small weapon. It also does not pour smoothly. Perhaps the channels in the rubber top need to be redesigned. For a coffee maker this nice, the Ratio 8 definitely deserves a better, lighter carafe. Thanks.”

“Hello, there is one critical design flaw that prevents me from giving full stars. The underside area around the showerhead is plastic and has exposed screws. The steam and condensation that builds up around the shower head during brewing causes water to build up on the plastic underside and drop into your coffee during brewing. As i bought this to have the most minimal contact between my coffee and plastic, it is disappointing. To help this I wrapped foil around the showerhead area and made a cut out for the shower head. This had helped allow the condensation to build up on the foil rather than the plastic. However this is a pretty big eye sore on my nearly $700 coffee maker. My wife thinks it’s hideous and is not thrilled about it. I would love if ratio would have an actual stainless steel piece fabricated that could slip over and around the shower head area so that don’t have hot water building up and perspiring off the plastic underside into my coffee. I would happily pay for this to have a more seamless user experience and remedy the aesthetics of my beautiful machine. Please consider having a stainless steel piece fabricated! Thank you”

“Considering that Ration Six brews wonderful coffee, and was priced accordingly, the Series 1 Thermal Carafe was an outright failure; hard to use, with a lousy pour -- would have been a disgrace on a Mr. Coffee. Series 2: Ratio had fixed the mechanical design problems, so it handles and pours well. Not sure how "thermal" it still is not. Should we expect hot coffee a half-hour after brewing? Probably yes in a $75 thermal carafe.”

“Hi Mark, how are you? Thank you for my R4 unit. From my initial 2x brews, I the R4 makes a decent cup of coffee (6 out of 10 rating). I noticed the water spouts are not consistent and pours uneven both times so far. I’m hoping It works better the next couple brews and will take of video. Cheers, TimWYoung”
