WAGO 221 Lever-Nuts 36pc Compact Splicing Wire Connector Assortment. Includes (16x) 221-412, (12x) 221-413, (8X) 221-415

Very easy to use. Seems much better than having to twist wires together in cap thing.

Easy to use

These connectors are the cats meow. So easy to use I almost considered redoing some previous work. Wire nuts are running for their lives from fear of being replaced.

Great concept/product. I will never use wire nuts again. More expensive but saves time.

These are amazing easy to use wire connectors. Comes with 2s 3s 5s. As I was upgrading to new switches and dimmers I quickly found that the wire nuts were eating space I didn’t really have and the connections weren’t guaranteed. These are quick and sturdy. I still add a bit of antiox when using aluminum (original wiring)

Works as described

Ive given up using traditional wire nuts in favor of these Wago 221 Lever-Nuts. Why? Because there is NEVER any guarantee when joining stranded and solid wires that a secure connection has been made. Its a crap shoot. Sure, you can tug at the wires in the nut connector to make sure the wires dont pull loose, but you have NO proof that the solid and stranded wires inside the wire nut are making good contact. Using Wagos you never have to twist solid and stranded wires together. Since the connectors are transparent, you can easily see that the separate wires are properly inserted and a great connection has been made. If traditional wire nuts were made transparent and you could see how poorly connected the wires can be inside (specifically stranded/solid combined wires) I bet you would stop using wire nuts and switch to Wagos too.

use it to install lights and work perfect, save you time

As a DIY, these things are fantastic. Saves a lot of time, very easy to use, & reusable if you need to make any changes. I strongly recommend them!

Far simpler to use than all other two/three/four wire connection systems. As firm a connection as soldering and black tape and much easier to take apart and/or re-connect when/if necessary; most important: takes up far less space/volume than almost any other connection system
