Got this to replace my 20 year old Hamilton Beach food processor, which really struggled with mixing dough and had a tendency to spill liquids. So far I’ve only used the Ninja to mix pizza dough, but it handles that tough job like a champ. In about a minute I get a velvety-smooth dough ball that would otherwise take me 10 minutes of kneading by hand! The spacious carafe has nice silicone seals so I don’t expect spills will be an issue.
