How we tested
Supermarkets suspend unripe bananas from tall poles covered with small hooks. The Nature's Way Banana Keeper ($3.99) miniaturizes this idea for the home kitchen. We hung underripe bananas from this plastic gadget and put others from the same bunch in a bowl. After monitoring the fruit for a week, we found that both bunches ripened and then turned spotty brown at the same rate. Our conclusion? Just stick with the bowl.
