Never seen these before but a great idea for temporary or permanent wire connections.
I have used similar wire connectors before but they were only to connect 1 wire to another and not two sided like this item. As these are reusable they are great for setting up and checking all sorts of wiring before you make permanent connections. As you can connect 3 different wires in and then out they are a fantastic idea. Guessing you could use for Live, Negative and neutral on a wiring circuit but don’t know if those wires might be too thick as not tried them that way. If you did though it would just be temporary as don’t think you would be allowed to use permanently with modern regulations. Just a quick and easy solution for testing that any wiring circuit works before you make it more permanent. I have just used them in a 1996 Saab that I have had from new and so handy for connecting modern audio unit and speakers to old style wiring. I think a great use would be in garden lighting where you have recessed lights and would make it so much easier changing bulbs by cutting existing wiring then connecting it back with these. Would make changing bulbs a one minute job.

Easy connections
These are a god send, Work perfectly and are decent quality for the money. Makes wiring so much easier and saves you lots of time. Holds the wire in good enough, and alot easier and quicker if you need to move something around.

Really useful item.
These are pretty good. Will hold dissimilar cable sizes. Handy for temporary - and not so temporary - connections.

Better than traditional screw connect blocks.
Seems to work reliably as a connection block. You can attach any number of them together. All are a one in and out through, so they can form any number of connect through ways, perhaps safer than traditional connector blocks with screws. As these are fully plastic covered. Just know that you must pull the levers to full 90 dgrees, as they may be a bit stiff, which also gives me confidence that they won't get loose.

More convenient
I got these as fed up with trying to wire things like a ceiling extractor fan in a cramped and poorly lit loft. I don't fit many such things and a few years ago when I had better eyesight and mobility I probably wouldn't have bothered with these. But it's nice to be able to wire a short length of cable to the fan on a bench in good light and then just use these to connect up. The 'Molex' type connectors would be the next best option and cheaper but these save time and frustration. It might not be me that has to replace the fan next time but it will be a bit easier to do.

Good quality and work well
There are clearly a lot of these types of terminal connectors on the market. These worked well on a number of different wire thicknesses. So much easier than the old screw in terminal blocks.
