- Ease of Use: Features like timers, LCD displays, and automatic shut-off simplify the process. A clear lid allows you to monitor progress. Choose a machine with controls that you find intuitive and convenient.
- Versatility: Many natto makers also handle yogurt, cheese, rice wine, and even black garlic. If you want to experiment with different ferments, look for a multifunctional machine with adjustable settings.
