I purchased the 2, 3 and 5 terminal versions of these. Like many others, I think they are a major advancement over wire nuts. Also, for many tasks these are much better than other push-in connectors because it's so easy to un-do and re-do the connections - this is helpful not just for electrical purposes but also for changing and re-routing the tangled nest of wires inside a crowded box. Some push-nut connectors have release mechanisms, but they can be much harder to use than the handy little levers on the Wago nuts. Another benefit of the lever-nuts is that you can easily test a connection before you finalize it, and there is no twisting & untwisting in the process, nor any need for separate clip leads etc. Some professional electricians might do this on the fly with the power on, but as a DIYer I never risk such testing with live house wiring. Set up proposed connection temporarily using the lever-nuts, go turn on the breaker to verify correct operation, then turn it off again and do the final cutting, stripping, connecting and box-packing. The next version I'd love to see would be double-row versions for six or eight wires - explained below. I've been converting most of the switches in my home to Z-Wave smart dimmers and switches. The two major issues with those are 1) the body of the device is much larger than the simple switches they replace, and 2) they require a Neutral pigtail to each switch. The small size of these Wago connectors makes it easy to push them back into the box, out of the way of the large smart-switches. Now, for the Neutrals, I sometimes use these Wago lever connectors to add the new pigtails, but often I need to add two Neutrals to an existing four- or five-wire bundle twisted together in a large wire nut. What I do then, is to un-twist the bundle, carefully separate and straighten the copper ends, and insert them into a push-in connector along with the new white pigtail wire(s). This is where the five-conductor Wago lever connectors can be inadequate - first because I sometimes need six or more positions, and second because spreading out all the wires in one long row is not always a good arrangement in the box. So in those cases, I use a two-row six or eight-position connector and do without the handy release-lever feature. Note that the Wago brand push-nuts (wall-nuts) are very good also, though other brands will do a similar job. Am important note when using push-ins vs. wire-nuts: I've found that when the wires are not twisted together as with a wire nut, there can be a lot of stress that tries to pull on individual wires, and this gets especially unpredictable when smashing a big wad of wires and connectors back into the box. So what I do is to pinch the bundle together and tighten it up with a nylon zip-tie about 1/4" to 1/2" (say 1cm) from the connector. This makes a strong bundle like wire nut would do, but it's shorter, smaller and a lot easier to modify later.

Much tidier, easy to see. Make sure you always do a pull test as you insert each wire (important) Watch out for ‘look alikes’. Stick with WAGO

Probabilmente troverete qualche elettricista riluttante ai cambiamenti che vi dirà che sono molto meglio i mammut o i cappellotti. Altri invece lo ammettono: sono molto meglio. Io mi trovo molto bene. Ho rifatto tutte le scatole di derivazione: non serve cacciavite, tengono benissimo, pochissimo ingombro, è indifferente “unire” cavi di sezione diversa (a volte può capitare). Sono molto veloci da montare. L’anima in rame non viene maltrattata da avvitamenti e compressioni... se avete un mazzetto di 7 masse da unire va benissimo quello che usate ora. Io li trovo facili, efficaci e soprattutto veloci da installare e comodi da maneggiare (faretti entra/esci, lampade o lampadari al posto dei mammut, li ho usati anche in giardino con nastro isolante autoagglomerante)... molto soddisfatto finora. Spero che il “meccanismo” che stringe i cavi nel tempo non si allenti...

WAGO Klemmen sind für mich die beste Lösung für schnelle und sichere Verbindungen. Die Handhabung ist extrem einfach: Hebel auf, Kabel rein, fertig. Die Verbindung sitzt fest und zuverlässig, ohne Schrauben oder Werkzeug. Ideal für Renovierungen und Installationen. Pro: ✔️ Sehr einfache Anwendung ✔️ Sichere Verbindung ✔️ Wiederverwendbar ✔️ Hohe Qualität Fazit: Unverzichtbar für jede Elektroarbeit.
