“We are enjoying our new ratio as we did with our previous Ratio 8 which we had for 10 years. We are very happy to have such a reliable coffee machine and great tasting coffee each morning!”

“I'm blown away by how bad the Ratio Six Coffee Machine White is. We've had a Cuisinart coffee maker for over 15 years, and it cost less than $100, but it crushes this machine in every way. Here's where the Ratio Six falls short: 1. The water pouring area lid is super loose, doesn't feel like it fits right. 2. The connection between the dipper and the top where you put the coffee is loose, creates a gap that makes a mess with the vapor and needs extra wipe downs. 3. The collecting pot and lid are loose too, doesn't feel sturdy. 4. The boost, brew, and ready indicators are pointless. 5. Brewing takes way longer than it should. 6. There's no warmer, which is a major bummer. 7. The coffee brews at a ridiculously low temp. 8. The white plastic looks and feels super cheap. Honestly, I'd return this thing in a heartbeat. The Cuisinart still kicks its butt.”

“We were really excited to receive this “non toxic” all glass and steel water parts coffee maker. It is beautiful and also very elegant. To learn that it does not have a warming pad and that the coffee once brewed gets cold so quickly was real bummer. We are keeping the unit and ordering the “thermal stainless vessel” however really bummed we have to take coffee and warm it in a microwave so quickly after it’s brewed. As a microwave we are also trying to exit out of our home in efforts to get more natural.”

“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.”

“Keeps coffee at a nice temp for a good stretch but requires preheating the interior with hot water before brewing. The carafe has a nice weight to it, but it feels imbalanced, almost excessively heavy. Pouring is a bit awkward, especially when getting the last of the coffee out. This flaw when pouring appears to be related to the spout design and the trade-offs made to accommodate the base of the dripper, heating area of the Ratio Eight itself, and volume of the carafe. Also the standard Chemex filters that fit the Ratio Eight glass carafe are an inch or so too tall for the dripper and this thermal carafe. Overall, I am happy with how hot coffee now stays hot for much longer, and can overlook the minor downsides of the carafe and dripper. Whether or not this will be worth the extra cost is dependent on individual preference and budget.”

“Honestly, I am so bummed out about this thing. It took so long to get and I finally get it and I did not realize and had no idea that it does not have a hot plate. My husband is more or less furious with me that I would buy an $800 coffee pot that can’t keep it hot longer than 15 minutes. I really want to return it, but I’m unsure of the return policy.”

Hi Chandler, we’re so sorry to hear you’re disappointed. We chose not to include a hot plate because keeping coffee on continuous heat can quickly affect its flavor, and our goal is to preserve the taste and quality from the first cup to the last. You have 30 days from delivery to decide if you’d like to keep your Ratio. If you’d like to start a return, you can fill out our quick online return form. We appreciate you giving Ratio a try and are happy to help with any questions along the way.

“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.”

“We were so excited to get our ratio eight series 2 but it’s been a total let down. The coffee maker CONSTANTLY overflows when we try to make a large batch. I’ve called and emailed customer support but after 4 business days, theres been no response or help. Additionally, the base of the machine is entirely white plastic now. When the coffee is brewing, it spits coffee out on the counter and base. After a couple of months, I highly suspect the base will be stained - even with vigilant cleaning. Overall, we’re disappointed and I can’t recommend the machine.”

“Didn’t get the Ratio Six. I was sent the fancy, fancy Ratio 8 by your shipping department. Even though the error was not mine, I was told I had to re-pack the coffee maker and run the risk of a 20% restocking fee if there was any damage. I had decided I did not want the Ratio Six either, but you would not issue me a charge credit until I returned the machine you sent me in error safely. The only way to avoid this unpleasantness was to pay you an additional $260.00. You extorted me. Such an awful experience!! My coffee maker will be in a charity white elephant sale at a large church in my city, with a hilarious note about this farce. And on top of everything, after changing filter brand, type, coffee grind, water to coffee ratio, I have never gotten a decent cup of coffee!! You couldn’t make up a more ridiculous product/service story than this. I think the Ratio Six will be a hit at the white elephant sale—should be good for something.”
