In most households, doors are often opened by turning their knobs. This is not convenient for children, the elderly, and the disabled, or under special circumstances (such as serving a dish with both hands). Mr. Open is a door knob handle made of silica gel added to a door lock. To open the door with this device on it, all you have to do is to push down the handle. The angle of the handle is adjustable to meet different users needs.
