After a recent renovation and new lights, I found these connectors (and their two-wire counterpart) to be indispensable for working with aluminum wiring in my home. I use an Oslatools torque wrench for proper tightening (required for these connectors). They are a bit more expensive but worth it. Many of the joints I made with it were later sealed with sheathing/siding and will never be exposed again in my life. In these conditions you really have to rely on good connectors.
