This gadget promises a tear-free solution to chopping onions, but does it deliver?
This gadget claims to deliver perfectly cubed onions and elegant batons of carrots, bell peppers, or apples with one punch of the hand-held chopper’s blades against its platform base. The tool did chop half a small yellow onion (and even cut it into a fine dice, after some careful rotation and a second chomp). But with a larger red-onion half, and then a medium-sized carrot, the operation failed: We found ourselves cautiously extracting suspended vegetables from the blades and poking leftover bits through the grid with the tines of a fork.
