When I first received this product, I thought, boy, is this going to cut down on the time it takes to wash and dry lettuce. While the lettuce, spinach (and vegetables) will eventually get dry, you have to manually pump the knob in the top several times for it to spin dry the lettuce, vegetables, etc.  For say a bag of romaine lettuce you first wash it then manually press the knob on the top like a child's spinning top several times, at least ten before your lettuce is dry and not completely dry.

Pros: The salad bowl is a very good size so it will hold a large salad.  It is made out of heavy plastic so it is safe for the dishwasher
Cons: Take too long for the lettuce, spinach, vegetables to dry. You have to pump the knob several times before it will spin lets say a minute
