The Tustin Lever doesn’t lock since it’s meant for hall/closet doors. The installation was relatively simple and the lever can be installed on either right or left-handed doors.  It seems well made and durable.  The Satin Nickel finish looks nice and blends well with any room style.  This model is suitable for anyone who has trouble using regular doorknobs or has their hands full.  It also features Microban protection which keeps the door hardware 99.9% cleaner than unprotected surfaces.  It’s definitely an improvement to my closet door.
