The holder is made of quite soft plastic, but processed sturdy and neat. The connectors are practical plug fixings. Stripping and tuck. But then only works with single wires 1.5mm really good, and not in finely-stranded with ferrules. Here also is missing a silicone tube for thermal insulation of the cable into the socket, the like could be provided. In a wall or ceiling, the cable must be stripped very short, because the space in the bottom of the base is very limited.
