“Great machine, but get the thermal carafe, the glass one isn't great, coffee gets cold too quickly”

Posted 8 months ago

“Hi - i am still waiting on a response about an issue with my machine sent 5 days ago i said the following Hello, I just received my Ratio Eight and on the very first use, it will not brew at all. Here’s what I’ve observed: order#59478 All three lights are blinking. There is no sound from the pump or heater — total silence. The carafe does not heat. No water is moving through the machine. I have followed all setup instructions, including filling the reservoir, seating the brew basket, placing the carafe, and running multiple attempts. The water tank is fixed and cannot be removed. It seems the unit is defective. Could you please advise on a replacement under warranty? Thank you for your prompt assistance. Best regards, Emily Aledort”

“Filter itself is nice but the product is falsely advertised as being compatible with the Ratio Six as part of their “plastic free brew path.” Be aware. It’s not. It’s almost impossible to align the pot and brew basket under the water stream to prevent spilling. I reached out to customer service both on social media and email and never received a response. Poor experience overall.”

“So far having a miserable experience with this on my Ratio 6 when brewing a full pot. Overflows and unfinished dripping with compacted grounds. Have significantly adjusted grind size, amount of grounds, all to no avail.”

“I love the look of this coffee maker and the fact that it does not let the water come in contact with any plastic. However, the coffee does not get hot enough when first brewed and because there is no heater under the glass carafe, the coffee does not even stay luke warm. I tried to order the thermos that goes with this machine, but it has been sold out. I ordered this coffee maker when it was at it's most expensive price and the following week it went down over $300.”

“This was delivered on 12/22/25. I ordered it as a Christmas gift for my husband. We used it after opening it Christmas morning and by Christmas dinner I noticed that the lights were blinking when not in use. It has progressively gotten worse (starting, with water dripping when not in use, stopping mid-brew when it is in use). We finally stopped using it two weeks ago when it stopped mid-brew and never restarted. It is now sitting on my counter with water in it we can’t drain. I’ve sent in at least 2 return requests via the website last week and no response. I want a full refund. We basically got zero days of a properly functioning machine.”

“I've been looking for a plastic free coffee maker for a long time. Note this is only plastic free if you get the glass pour over carafe. I wish they didn't use plastic for the coffee brewer piece. None of the available machines have the functionality I need which would be an auto on timer and automatic size selection of the brew. I don't have much time in the morning to mess around with coffee brewing. With that said, this seemed like one of better options. I kept this because the coffee tastes delicious. I used a ninja drip machine and was blown away at the difference in flavor.”

“I’ve contacted customer service two different ways, with no reply. but we may be returning ours. We just purchased and although we love the glass, coffee isn’t as hot as we’re used too upon brewing, and I did purchase a thermal pot as well with a lid. I’ve put hot water in to warm the thermal up before brewing, but it still doesn’t keep coffee hot longer than 30 minutes. Coffee comes out “warm” at best”

“I clumsily shattered my previous Ratio Glass Carafe on a marble counter and I needed a replacement for my Ratio 8. I do hope Ratio will continue to offer these for Ratio 8 (and Ratio 6) machines, as I much prefer the Chemex style cone filter to a basket style filter for automating my pour over process!”

“I love everything about this beautiful coffee maker- the look, the sound it makes when it brews, how easy it is to clean, and of course the coffee! There’s just 2 things I wish was different. First, I wish the button was not touch sensitive. A press button to turn it on/off would work better for me because the coffee maker sits on my counter next to where we get our drinks and is accidentally turned on often, also when I move or turn it a little to make coffee. The only other thing is I need to buy the other coffee pot now that keeps my coffee hot because I am reheating constantly. I love the look of the glass pot so wish it could stay hot & didn’t want to spend anymore money. Other than that, it’s amazing!!!”

“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!

“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.”
