It can be a tough chore to get tight jar lids opened. Emson believes it has the solution with its Robo Twist jar opener. A woman is shown placing the kitchen product on top of a jar. After tapping a button, the Robo Twist tightens itself on the lid and quickly twists off the top. Robo Twist may be especially useful, the company says, for older folks or people with arthritis, who might have trouble opening jars.
