“I do not have it in my possession as of yet. You guys don’t ship to Hawaii so I had to have it sent to a friends place in Santa Cruz. He should be arriving with it within the next few days. At that time, I can let you guys know what I think”

“Beautiful, amazing coffee, but no burner was a surprise I wasn't ready for. I didn't even know that was an option with coffee pots.”

“I like my ratio 8 -- overall the coffee has been good. But the issue I have is that a lot of the times that I make 7 or 8 cups of coffee the coffee spill over the filter and grounds seeps under the filter. I am wondering if there was an issue with the design and if other people have experienced similar issues.”

“Makes a wonderful cup of coffee. Extremely balanced. Issues that we have had are: 1. Takes an inordinately long time for coffee to completely drain from the filter. Coffee is set for as coarse of a grind as possible. We have ordered Ratio stainless steel filter and hopefully this will correct the problem. 2. When brewing a full pot, coffee splashes out of the top of the cover a bit. 3. The brew switch is extremely sensitive. If barely brushed while wiping the counter it turns on starting to brew. At this point we need to replace the water, coffee and filter. 4. Not a complaint but it would be nice to brew a larger pot.”

“I got it only because it came in a bundle. There’s no info with the product about where it’s supposed to go. The website has a vague statement about putting it under the carafe. I put it under the carafe in the coffee maker - but then it would not brew and all three lights flashed.”

“My coffee overflows every single time with this filter, no exceptions. Customer service was not helpful at all either. It's been weeks, and still now response. Would NOT recommend.”

“Terrible experience overall. On my first brew I noticed that there is a plastic surface that was not mention on the website that has contact with hot steam that then also drips back into the brewing processed. I have reached out for questions concerning this, only to get an AI response several days after emailing them. I am still waiting on a human response now weeks later. I've lost all trust in his company and product's safety.”

“My Ratio Four coffee machine is beautiful. It makes my coffee experience delightful. There are just a couple of things that I have to get used to. For example, when I first removed the basket to take the coffee grinds out, the hot coffee that remained in the basket came out from the bottom and went on my hand. The other thing is the power button, it is in a spot that is easily touched when putting the basket back in place. Other than that, I love the Ratio Four coffee machine.”

“I don’t think it’s actually an 8 cup pot because when I fill up my ratio, the pot overflows unlike the all glass version that the system came with it never overflowed so it’s kind of disappointing”

“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.”
