The Greenchef Flen mixer has an Anti-slip foot feature that helps prevent the mixing of tough ingredients, such as rice and dal, which can make those spicy chutneys and smoothies. Its 1HP motor helps make the batches of food easier to handle. These jars have lids that are extra tight to prevent the contents from coming off. Also, they have a lid lock that prevents the lids from coming off. The 3-speed control knob lets you set the speed.
