Centrifugal juicer is the best way to enjoy fresh juice quickly. AICOOK centrifugal juice extractor comes with the promise of making fresh juice in a minute. For better juicing, it also has a dual-speed function. The low-speed option(13000-17000 RPM) is better for making juice from softer fruits and vegetables like grapes, oranges, and tomatoes. For hard fruits and veggies like apples, carrots, and celery, you can use fast-speed(17000-21000 RPM) mode.
