There should be a handle on the ceramic part that holds the filter and coffee if you want to take it off before it finishes dripping. The craft is not keep the coffee, very hot, it does not seal completely with the stopper. It’s difficult to pour the coffee.

The carafe broke on its first day. Very fragile!

Hi Mark, I purchased a Ratio 6 and though very pleased with it, thought the carafe was a bit clunky. Our family takes our coffee very seriously so we decided to splurge on a Ratio 8. We think the 8 makes better coffee than the 6, which is still very good, and we feel the carafe is much nicer for pouring. But, the water reservoir on the Ratio 6 does not empty completely after brewing coffee and that is a problem. I don't like old water to collect in the machine. I've actually gone back to using the 6, which is a shame. Have any other customers had this problem? Could I exchange it. Or, what would you suggest? Thanks.

Look is nice, but I think overall function and design of the Ratio Six is a little impractical. Personally not a fan of how the brew basket has to remain on top of the carafe while brewing, whereas other SCA coffee brewers have a holder for the brew basket. This allows for a “stop flow” capability so in the event Coffee is needed to be poured immediately, the carafe can be removed mid-brew. I personally also think the overall size is a bit bulky and too many individual components. Still brews a great cup of coffee but I prefer the Moccamaster and would not purchase another Ratio

I’m sorry to say I returned it due some issues with difficulty to use. I’m awaiting my refund.

The coffee is good, but the design of the Ratio Six is disappointing. Customer Service simply agreed with me, and they don't seem to mind the issues.

Hello, unfortunately our thermal carafe has started leaking from the metal rim. Meaning whenever we pour coffee from the carafe, coffee leaks onto the counter. Is there a way to fix this or replace it?

Not the best design. It pours messy and if you don't set the boot over the basket perfectly, you'll end up w a wet country and no coffee.

While I like the idea of the ratio six, there are a few things I think could make it much better. The heat guard piece is awkward to remove, and splashes water/coffee droplets when you take it off. Also the carafe is not nice to pour from, it’s difficult to get every drop of coffee out and some always drips down the side. Also while the inside is stainless steel the outside is plastic. Wanted to love the machine but I’m returning it.

I love the design and the idea of saving paper, but it creates a muddy cup of coffee.

I cannot review a product that was manufactured, then a defect found at the factory, so it was not shipped and I have received no word since 12/23/19.

Hello Thomas, Very sorry to hear about your experience! Our factory here in Portland is more of a workshop, and we assemble and test each unit by hand. When anything is discovered that isn't up to our high standards, we do everything we can to make it right. I've sent you a note directly. Thanks for letting us know!
