Review on 🔌 Enhance Electrical Testing with 5Colors Retractable Sheath Banana Plug Stackable Wire Solder DIY Connectors by Boondo Viswanathan

* The tips are fairly pliable, with plenty of spring leaves and a good relief cut. I've tested them with every banana jack I have on hand and they've made good contact with all of them with no issues.* The retractable shells move on their own metal spring and retract with ease when inserted into an unshielded or custom plug Inserting the connector has teeth to hold the insulation on the wire. This is where I got confused. I bought several 18AWG silicone covered wires with an overall diameter of 2.3mm to fit into these connectors. Unfortunately, 2.3mm is more suitable for a "hot dog in the hallway". I'm going to order some 14AWG wires with an overall diameter of 3.5mm (which is what the description says) so I can have a nice and working wire. I can leave the 18AWG wire for some of the signal wires, but I'd like rubber grommets to fit it into these connectors. I know the saying. "Free landings sink ships" and so on.
