content: I find this chopper to be frustrating and ineffective. Food is always getting under the blades, pushing them up so that the blade is no longer caught by the drive shaft. This happens chopping something as easily chopped as onions, so forget having any success at the harder items, like nuts!The button is also very difficult to press. My young children used to help out on the kitchen by using the mini-chopper, but everyone except my 9 year old are unable to do so.I'm shopping for a new model...and hoping for better luck!
