Have been using wire nuts and electrical tape for connections my whole life. Had 25 mr16 transformers to bypass in a huge section of ceiling and was dreading working with my hands overhead through 4inch downlight holes in the plaster all day.I saw your product and ordered fifty xf2 two wire connectors to try them out. I prepped all the wires in the ceiling and connected all twenty five lights in under an hour. The finished result was a solid, strong connection that looks clean and tidy. All twentyfinve lights are working and back in service.Thanks, I’m a covert!
