I am lazy to pick tomatos one by one and check whether they are ok. I would rather buy a whole pack. Sometimes there's a bad one carefully hidden so it isn't visible from the outside. How about a small device that would beep whether the pack is ok or not. I am sure there must be some particles in the air that could indicate this.
