Delgada 100 PCS Compact Wire Connector Nuts Kit -Reusable Push-in Terminals for Quick Wire Splicing. Compatible with Stranded, Solid, and Flexible Wires. Includes 2-5 Ports for Universal Wiring

Secure connections it appears. I use these for 12V and 24V DC Distribution in Ammo Box Stereo Builds that require both voltages. Makes things so much easier...

Handy, practical device for wiring my complex model railroad. Kept wires neat and secure with easy disconnect/reconnect making testing easy!

Way better product than the old wire nuts. Easy to use and these were much cheaper than the higher priced name brand.

These are great and very useful

So far I've rewired outlets, ceiling lights, and an outdoor dusk-to-dawn light with these. I personally hate screw on wire connectors and these seemed like a good place to start. The switch can be a little difficult to open, but the tension on the connected wires fills you with confidence it won't let go. I'll buy more when I run out. I have a lot more wiring projects around the house to do.

O have tried many products in the market, this one actually keeps the wires in contact never loose wires once its on.

I had a place that I just couldn't get a regular wire twist tie to stay connected. these made the connection quick and easy. In another application, I replaced a controler in a touch lamp, and the color codes on the old and new units were different, even though they used the same colors. Correcting the circuit was quick and easy. simply detach two wires and reconnect. No fighting with several wires having to be straightened, realigned and retwisted in limited space. I will buy these again...if I ever run out...

I recently used these to install an iDataStart in my Subaru Outback. These made the whole process so much simpler. I know taps would’ve been better but I didn’t realize I didn’t have any of them until I had started the process. It’s been a week now and everything is working perfectly. These are much better than crimping wires and wearing out your hands.

No need to buy the brand name ones, these are great and work really well. Easy to use and not a bad price at all.

I was a bit leery about these connectors since they are not CSA or UL approved and they cost one quarter of what Wago connectors do (which are made in Germany and are approved). However, I have used the Delgada connectors for two jobs and they seem to be far superior to the twist-on connectors I have been using for decades. I used a spring scale to measure the force required to pull a wire out of the connector and it took 25 lbs. Since the wire can rotate freely when it is connected, it makes it very easy to arrange the wires neatly in a box. The connectors are especially good for connecting stranded to solid wires, where you can never be sure that a twist-on connector is making a secure connection. Obviously no electrician would use unapproved connectors, but for the home handyman, the Delgada connectors are a huge improvement over traditional connectors. However, you should aware that a wire can be easily removed from the connector if it is twisted while being pulled. If a wire is pulled without being twisted, it takes over 25 lbs. of force pull it out of the connector. However, the wire comes out with little force if the wire is rotated while it is pulled. This could be an issue when the wires joined by a connector are stuffed into a switch or junction box. You should verify that all wires in a connector are still fully inserted into the connector after they are positioned in the box. Note that Wago connectors, which cost 4 times more have exactly the same problem.

First order came and the case was broken with about 10 or 12 peices missing.2nd time it came it was perfect, new condition with all pcs ..great!

Have used traditional Merret "twist on" connectors all my life. Decided to try these. They are well made and very durable. Once the wire is "locked in" it is almost impossible to pull out without releasing the switch. They come with a guide on the back to show how long to strip the wire. Great for all types of wire - solid, twisted pair, frayed. Like that you receive many different size combinations in the one box. Satisfied with my purchase.

They're easy to use and perhaps better than marettes?They also work well for people with REALLY, really skinny fingers.
