SUPERNIGHT 10 Pack 2 Pin LED Connectors 10mm with16.4ft 22 Gauge 2 Conductor Extension Cable Solderless for Waterproof 10mm 5050 5630 LED Strip Lights, Strip to Wire Quick Connection Without Stripping

I used 4 connectors for connecting the 8 mm strip light sections. The wire connection side has a much better chance of first time success. A couple of connections required multiple attempts to make the connection. Make sure to use a multi-meter to check the connection after each connection made. I found that the contact did not really slice through the insulation of the included wire after the clip was clicked in. I had to open the click again and use a small screw driver to press the wire in before closing the clip.The strip light side contact has similar issue. If the contact pins come from the top, it would make the connection much better. With this design, the contact pins come from the bottom. Even the pin pierced through the contacts from the bottom, there is a good chance they do not make contact with the solder pads. I found that if I tin a thin layer of solder on the solder pads before putting the connector on, the contact pins can bite into the solder, making the connection more consistent.

Worked as described. A bit of an issue making the actual connection but be patient and it will work.

I bought both the 10 pack 4-pin 10mm LED connector and the 10 pack 2-pin LED connector for 8mm (non-waterproof) light strip, and I got extremely mixed results.TL:DR: the "10 pack 4-pin 10mm LED connector" by itself is 5 stars (bit of hassle to get the hang of it, but it works!); the "10 pack 2-pin LED connectors for 8mm (non-waterproof) strip" by itself is 0 out of 5, yes, ZERO star product, piece of crap.Now, the "bear with me" part...I was in the process of kitchen remodeling. One of the features I'd like to add was undercounter lights, and I happened to have a spare set of LED strip laying around, so I wanted to install it. For aesthetics and ease of use (avoiding certain large appliances and the washing sink in the middle of cabinets), I needed the LED strip to be cut into multiple sections while maintaining the same one power supply source to save electrical outlets for other kitchen use. Some googling later, it occurred to me, I needed "extensions" or "connectors" to bridge my cut LED light strips, and Google led me to this product page.My spare set of LED light strip to begin with was 4-pin RGB waterproof type, so I purchased the connectors accordingly. Once arrived promptly, it took me some getting used to, but overall, it works: as shown in my first 2 pictures.However, I had a change of heart...Because my RGB light strip doesn't produce pure white (more blue-tinted white than pure white), it bothered me to no end, so I decided to forgo the working LED light strip I already successfully installed, and went for mono-color "pure bright day light" white LED light strip. All the ones I could find on Amazon are 2-pin connectors, so I ordered a second set of "10 pack 2-pin LED connector for 8mm non-waterproof light strip", thinking the product will be just as good and even easier to install for the 2nd go-around. WRONG!for these connectors to work, one end that connects the light strip needs to have the metal teeth cut into the contact pieces (2-pin or 4-pin) on the LED strip, the other end on the connector needs to cut through the plastics around the electrical wires (2-wire or 4-wire) to make contact with the metal core to transmit electricity (but NOT strip the plastic ends completely like a wire cutter, otherwise the teeth will have nothing to bite down to to secure the wires to the connectors). As demonstrated in my 3rd picture, the "2-pin connector" product fails to cut through the (black-red) wire plastics, it barely squeezes the wires. Either the clamp mechanism is not designed well to cut these black-red wires, or the black-red wire is of crap quality that the plastics are too stiff for the teeth to cut through (or answer C: both). the 2-pin connectors aren't able to cut through the 2-wire cable, hence electrical connection cannot be re-established. all told, I've only tested 2 connectors out of the box of 10, I didn't bother to test the rest of them, 20% failure rate is high enough for me.But I wasn't just gonna sit on my a*s and staring at this mess of crumbled wires and LED light strip and complain til my hearts content (well, I am now, but in aftermath). I had to fix this, a mess I've paid money for, twice. I had to get it to work.In the end, after tedious trail and error, I got it to work: I ditched the crap black-red wire from the 2-pin pack. I stripped 2 wires from the 4-wire RGB cable that came with the 4-pin pack, used the 4-pin connector to make good contact bite marks on these 2 wires, then installed these 2 wires with good bite marks into the appropriate end on the 2-pin connector. The other end of the 2-pin connectors bite into my 2-pin LED light strips (because the 4-pin connector cannot bite into and securely hold onto thin non-waterproof LED strip, without the layer of clear silicone, the 2-pin connector is designed for these paper-thin LED strips). And as the French would say: Voila! It worked.But you see, how tedious this process was, so please forgive me for not having any more patience to grab my cellphone, take a shot of the working end result, run back to my computer to upload these pictures and share them here. Just take my word or leave it.If your application is 4-pin LED light strip, the appropriate connectors should serve your needs well. If your application is 2-pin LED light strip, stay away from the 2-pin connectors and learn to solder...

The connectors worked as advertised. It made a very solid contact to the LED strip and the wire without having to use solder. Having made several terminations, I would recommend making sure that you peel back at least a 1/2 inch of the adhesive covering on the LED strip before inserting it into the connector. Than make sure that the strip goes all the way in or it may miss the connection when the cover is closed. On the wire end make sure the inserted wire goes pass the metal tangs before closing its cover. A little pricey but if you are not skilled at soldering or don't want to bother with the effort, and only a few connections, these will definitely do the job.

I spent over an hour troubleshooting these connectors (on one string connection) just to figure out that the connectors were not making a solid connection to the copper leads on my LED strip lights. There are two prongs that punch through the strip lights from the back that are supposed to complete the circuit. This design does not work well. My fix was to install the connectors backwards. In other words, instead of putting the sticky back in the connector and then closing it on the light side, I put the lights down and closed the hood on the sticky side of the lights. This way the copper leads are down against the two prongs and it made a good connection. After that these worked well.

This was my first time installing a led tape kit. It took me a few times to make good connections. It was me and not the connectors. You don’t need to strip the wires. Be sure to fully insert the led tape and the wires.

Take time to read this wise advice from me, guard thine own sanity (Shakespeare, I think). I don't normally write reviews, but I would be doing mankind a disservice if I failed to tell the world how HORRIBLE these connectors are. I purchased led tape light from Superbright LED. The connectors that I needed were on backorder, so I ordered this kit from Amazon. What should have been a two hour job turned into two days of frustration. The connectors are designed to accept 22awg wire on one side, and 10mm tape light on the other. The side that accepts wire seems to work ok, but the side that accepts the tape does not. The reason these connectors don't work is because the tape side of the connector has two brass blades or barbs that are designed to peirce the thin copper strips that run through the tape. The barbs are not tall enough to make a secure connection. Once I got other connectors from Superbright LED the difference was very clear. The barbs on those connectors were about 2mm taller. Avoid these connectors from Amazon.

They worked great, just as they were suppose to. No complaints
