Wire Connectors 30 pcs, 221 Series Electrical Connectors Assortment with Case, Includes 221-2401, 221-412, 221-413, 221-415, Compact Splicing Wire Nuts

There are similar push-in connectors available. What I like with these ones is that you have this little lever to hold the wire, but also makes it easy to open and reseat if needed. If you got multiple wires in one connector, you can remove just the one you need. Very simple. On top, they safe some space in the box as they are really flat.

Takes up less room in the box, super easy and fast. After a few hours of twisting the traditional caps, my fingers feel raw. This is a good upgrade even though they are expensive. There are a few cases were these are necessary such as a really tight box. Other than that, the traditional caps work fine. If you have the cash, go for it.

The Wago 221 lever connectors pack here is great. There is a lot of variety including the in-line pieces. They are very easy to use to connect multiple wires together and are generally much easier and safer to use than wire nuts.Some people claim that these cause wires to get hotter than wire nuts, and researching this, it is true, but the wire and the connectors are still well within their working range, and do not pose a risk.

Would prefer fewer single wire connectors but I knew the quantity when I ordered them. Anyway, super easy to use and stuff back in the box saving room in smaller switch boxes. Especially for some of the newer wifi switches and dimmers. Never have a wire nut come off again whether by accident or using the wrong size.

These wago wire connectors are so much easier to use than regular wire nuts, all you need to do is strip the wire back to the correct length and lift up the lever insert the wire and close the lever. No more twisting the wire together. For my application these connector worked perfect. The connections were tight and secure. The connectors are also re-useable

These things are great, I am a DIYer and prefer to do my own wiring if I'm able to. These things are great because if you are doing things, you don't have to worry about wire nuts and messed up connections. These things are sturdy, reliable, and best part is just like a wire nut you can easily undo it and make changes. It is also awesome when you have to make pigtails.

If you like doing your own projects thus is a most have tool, fast and efficient work with this little device.

These connectors are just the thing for quick connecting of conductors, especially those of different wire gauges. Because each wire is inserted individually, there is no hassle of pretwisting or trying to line up several conductors for a wire nut. The inline variety are perfect for extending wires damaged by aggressive rotozippers. Just strip the end of the short wire, clip on the inline connector and clip on a pigtail. Nothing could be simpler. I highly recommend this product

This makes connecting wires so easy. Much better than marrets.

Easy to use and great space savings.

These connectors are very easy to use and allow for for neater cable management in electrical boxes. They make changing receptacles, switches, lighting etc., easy to replace in the future if the need arises. Much better than marretts.
