Totally worth it!
Works great for hummus. It's easy, tastes better than store-bought because you can use fresh lemons and high-quality olive oil, and you can customize it by adding things like peppers. We also make frozen desserts, almond butter, flour from whole grains, and of course super smooth smoothies. We average using it once per day, sometimes multiple times in a day.
