Excellent product! Used it today to chop up items for a beef stew for my wife: potatoes, carrots, green peppers, onions and parsley. It only took seconds to prepare each item. The onions and parsley in particular saved a lot of time for preparation.
I like the large glass bowl, the non-slip perfectly fitted circular silicone mat, the tight fitting cover and the powerful top mounted motor. There are four cutting blades with a metal connector (not plastic) to the motor shaft, and the device does have a safety switch so that the motor cannot operate the blades unless the motor is firmly placed upon the glass bowl. There is also a silicone gasket between the cover and bowl.
One other comment - another reviewer mentioned that the metal pivot on the bottom of the bowl which the cutter blades spin on is secured by a screw which can come loose. Well, as a mechanical engineer I proactively fixed that. When I received the product, I removed the screw and applied a couple of drops of medium strength Loctite and securely tightened the screw to the pivot. In the absence of oxygen when the fastener is very tight, Loctite cures and forms a very strong mechanical bond. Of course, a week later when I went to use the product, I thoroughly washed the bowl and all other components, except the motor.
Worked perfectly and had great stew!
