A perfect solution for connecting wires and nice for wire pairs such as speaker wires. These are a must in your electrical tool bag. Very quick easy to use for stranded or solid wires. Only issue is size is a little big.I also like the Ideal In-Sure push in wire connectors for connecting wires in a switch or outlet electrical box. they come in 2 port for connecting 2 wires, 3 port for three wires and 4 port for 4 wires. Easy to use and dont take up a lot of space in the box.
