Their Ratio Four is really good: simple on/off, bloom choice, no frills, and they have very much enjoyed it.
“My ratio 4 is really good just on off and you can select big or small bloom if you want that’s literally it.”
Happy with their Ratio Four as a small-batch brewer.
“The Ratio Four is worth considering as a small batch brewer. Maybe a little slept on. I'm happy with mine.”
Their Ratio Four is pretty good and lets them swap the dripper.
