Review on 🔌 Convenient Self-Stripping Electrical Connectors: Terminals Assortment for Easy Installation by Eric Garron

Very versatile. You can remove the metal insert and mix and match colors. I like to take the insert out after pushing the wires in, and then solder it, put it back in the case and latch it. You can file the insert gap to fit any wire size (within certain limits). I used them a long time ago and was glad to find them again. Many devices on the market today cannot be modified for such custom installations. I'm glad they still exist.
