This is the only wire connector I would trust when using aluminum wires in high current (20A) circuits. At over three dollars apiece, they're quite expensive. You also need a torque screwdriver to install them ($50 or more), which is an additional cost. Don't use them if you don't have them. Care must be taken when working with aluminum wire and the work must be carried out correctly. (The hell with the expenses.)
