The wait is finally over and well worth it! I saw the demo at the SCA in Portland and was chopping at the bit to get one. The size is perfect. My first cup was outstanding, very smooth and balanced. I used a bright Kenya, and I was able to taste some fruit notes and plenty of clarity. I did a side-by-side comparison with the Fellow Aiden, and I found the Ratio 4 to be the better-tasting cup. I prefer not to deal with settings. I highly recommend this brewer. You get the benefit of a pour-over without the hassle of timing, and it has the built-in bloom feature. It does it all for you. I can now retire my Ratio 6 since it is larger than my needs. I have tried it with Kalita Wave, Hario Mugan, Hario V60, and Hario Switch. They all work!

Received my Ratio Four after pledging for it on Kickstarter. The cups of coffee it's made so far are divine! The bloom cycle really lets the taste of coffee pop out. The size of the machine is compact and its design is sleek, elegant. It's in perfect time for the winter when I plan on hunkering down at home, away from the cold and getting some work done.

The coffee machine has been a fun addition to our kitchen. We already have the Ratio 8 and use it as our daily driver if you will. This one comes out any time that we need one more cup later in the day. The coffee brews quickly and tastes great. I've not been able to use the Hario V60 2 since it's 1/4" too large to fit with the included pot (or our usual coffee cups.) While it would technically fit in the space, there isn't enough room to actually get them INTO the machine. As such, I would need to order a smaller size, or brew into a much smaller cup. That and our lack of counter space to have both brewers out at all times are my only complaints.

Makes a great cup of pour over with such simplicity. Makes the morning easy without loss in quality. Also loving how compact this is. Fits in a small space on my kitchen counter without needing to manhandle for operation. Not to mention, it's very stylish.

I have tried hard to find a small brewer that made good coffee. Usually the smaller brewers aren't as good as their larger versions. This brewer is lovely. However I am very disappointed they provide no sample filters. The smaller filters are not as common for sale as the larger ones. It's a very bad experience to wait so long for a brewer to finally get it and not be able to try it out due to lack of any sample filters. I guess Ratio would rather made an extra 1 cent vs offering a better coffee experience.So be aware if you buy one, you might not be able to use it right away.

Hi Dennis, Very sorry we couldn't provide filters inside the box, at least on our first production; cost was not the issue, but rather finding filters that fit in the filter basket and don't overflow. We will keep working on it! Meanwhile, we're sending you a bag of our filters at no charge.
