Review on WAGO 221 Series Splicing Connectors with Compact Case: 25pc Wire Connectors Bundle - Includes 10x 221-412, 10x 221-413, 5x 221-415 by Josh Flanagan

I did some research on this product before purchasing it because I couldn't believe there was anything good in it as it is not available in regular stores is, but Reddit seemed 100% sure to me that this is the REAL way to connect wires, so I gave it a try. I was very happy with the result. Extremely easy to use, very small but still big enough to accommodate large cables, and each port can handle up to 30 amps (that's a lot more than a regular switch can handle). Overall I am very happy with my choice.
