This is an ingenious device, it functions so well that I'm at a loss for words, it's simply incredibly easy and useful.

Very useful, much easier than wire nuts for a large number of wires. Seems that extending circuits this way is very common, so it's nice to have a part like this that makes it easy to do properly without overloading a wire nut.

These are great. In response to some other reviews, here are some thoughts.The wire must be straight and be pushed straight in. The slightest curve or twist will make it impossible to get them in all the wayWith respect to them falling out, I do not think once they are fully inserted there is an issue. The problem is if you get it in the hole but not all theway it might come out. always test your insertion by trying to pull it out. Also check visually that you can see the end of the wire in the clear section of the clamp. You will eventually be able to "feel" the wire push into the "point of no return" in which the connection is permanentI have never trusted mw wire nutting skills for any more than 3 connectors, and these are great.

I'm sure that there is a Super Secret Professional Electrician way to attach a whole bunch of ground or neutral wires, in a single wirenut. I do not posses that secret, and this is the best solution I have found.I have added many double and triple gang boxes to our house as I've rewired. Some of these have multiple 3 way switches. Counting pigtails, that's a lot of ground and neutral wires. These push in connectors let me tie together the two grounding pigtails to the dimmers, the grounding pigtail to the box, the ground for the line-in 2 wire romex, and the two grounds for the 3 wire romex heading to the other 3 way switches. That's 6 wires, two of which are stranded. I bought this eight wire model because it's always nice to be oversized. I have some of the four wire Wago connectors that I hardly ever use: four 12 or 14 gauge wires in a regular wire nut isn't an issue.If the wires have been stripped and twisted appropriately, they will seat nicely in these connectors. I gently grip the wires I wish to insert with my needle nose pliers so that I can be sure that I'm pushing straight in with enough force to seat the wire.Solid wire can be wiggled free by twisting and pulling. The work it takes to remove a solid wire is beyond what should happen from flipping switches or inserting and removing plugs. I am in the habit of using a tiny ziptie as strain relief on *any* connections with pigtails, even when I'm using standard wire nuts. The pigtails are the only wires I have the slightest concern about coming loose. The ziptie gives me peace of mind.

Update: I didn't like these at first while I was dealing with stranded wiring while converting VERY old banks of fluorescent lights to LED.Lots of wires connect together.If you are working with solid wiring- BINGO!If you have stranded wiring, order the proper wire nuts & the proper amount of solid wiring. Stripping the stranded wiring, twisting them, and adding a solid wiring to push-in, still much easier than trying to wire nut bunches of wiring.I LOVE these! And getting some wire nuts & solid wiring was worth it.

I was made aware of these through another Amazonian's comment. I used them to connect 4 LED lamps to power. Worked great. Since I was working overhead, I really appreciated not fighting with trying to connect 5 wires with a wire nut. I had both 16 and 12 gauge wire and this device held them all securely. I wish I had known about this product earlier.

I wish I would have found these magical innovations years ago! This makes wiring SO much easier and safer. More so with more wires; trying to get a wire nut on a bunch of wires van be challenging in tight spots and can be dangerous if not done correctly. These are easy to use and speeds up your wire job.

For electrical work - these are the best things since sliced bread!! I have 4, 6, and 8 connectors. They take up less space than the "twisties" and you know each wire is well connected. Not to mention they are much faster to connect. Highly recommend them
