A ring brew group has less mass than an E61. It warms up faster and uses less power in continuous operation, but it maintains temperature less consistently during rapid consecutive extractions.
With Flow Control you manually control how quickly the water runs through the coffee grounds: start slowly, then increase pressure. That takes the edge off acidic beans and gives you an extra adjustment. Without Flow Control the extraction runs at a fixed pressure, and that is enough for most recipes.
The machine can be permanently connected to the water line but does not have to be. When plumbed in you do not need to refill, but the location is fixed and an installer is required. A water filter in the line is then mandatory, not optional.
You can store extraction volumes and recall them at the push of a button. If you prefer to stop by hand you can still do that.
58 millimeters is the most common size. Baskets, tampers, levelers and distributors are available for it from many manufacturers, so you are not tied to an unusual size or a single supplier.
Settings such as temperature, pre-infusion and extraction volumes can be changed via the app instead of through key combinations on the device. Practical if you want to save recipes; the machine also works fully without a phone.
