28 Pieces 3 Pin LED Connector LED Strip Solderless Light l Shape Lights Extension T Shape Solderless Adapter Connector 10 mm for WS2811 WS2812B SK6812 Strip

Somewhere along the cabinet project of using these, I ended up soldering the led to the prongs on these connectors. If your LED strip has a flimsy backing, sometimes you have to go in sideways at an angle and not straight into the track or else the led strip crumbles and folds like an accordion.(see first photo) So, to prevent this; if you already have purchased the strip just solder the points, or try to go in at a slight angle and then after put the other corner in after you have the left or right angle started. Other than that pretty decent product!(if you have a issue with lighting dying at a long strip, find the first connector that ends the light on, and see the next one in line is off? That means the 'solderless' contact prong is crooked or not a solid connection anymore, this usually happened to me after sticking it under the cabinet. Hope this helps someone else out)

just recently finished up my latest PC build and got a set of LED light strips (Amazon ASIN B08GSCJPMD) for accents inside the case. The LED strips were longer than I needed, and I wanted a cleaner install than 12 inches of loose wire at the junctions for that kit. So I got THIS kit of ARGB 3-pin couplers.The short story: These work! I got my LED strips mount around the inside of the window in my case. I recommend using a powered ARGB hub.The long story: Your motherboard probably doesn't put out enough power to properly run a LOT of LED lights off of a single ARGB plug. I ran into a problem when installing my LED light kit and using this couplers kit. The further along I got, the less the LED's worked properly (I did have a 24-cable motherboard extension kit as well). But the LEDs were doing weird things... They would not light up the correct pattern the AURA software was sending, and the LED strips pretty much wouldn't work after the 2nd junction with these couplers. It's as if they weren't getting enough power. And after a couple hours of trying to make it work using different coupler pieces, trying to modify them thinking it was bad connections (based on some other reviews here), I finally came to the conclusion that they just weren't pulling enough power through the motherboard 3-pin ARGB plug - and I have a brand new ASUS Hero VIII mobo! I finally decided to get a powered ARGB hub (Amazon ASIN B08T1SM5CW) as those draw power straight from the power supply and the only control signal from the motherboard. BINGO! Now with the LED strips and LED mobo cable plugged into the hub and powered by the power supply, all the lights worked perfectly as they should! And all the junctions I used this coupler kit for worked great!Overall these worked great for me. I suspect that others that have issues may be running into a POWER issue, not a connectivity issue. I did make sure the click the white covers down very tightly so they stayed closed. These get a recommendation from me.

I run into a few pieces do not keep a constant pressure. This leads to some joints not lighting past that joint. If you push on it a bit they will light. If you mess around with them for awhile they will stay lit. Still easier than joining by soldering wires.

Ignore the glowing reviews. Ignore the few swan-song successes people might have with these connectors - they don't work, and even if they do for some people, they aren't worth the risk. These connectors are single-handedly responsible for me having to trash two sets of perfectly good LEDs. Because these connectors are the only options for 3-pin LED strips, I'm starting to think the 3-pin design is simply incompatible with any type of connector. If you have a 3-pin strip of LEDs, DO NOT attempt to connect them. If you're still looking for LEDs, and wish to use connectors with them, too, be sure the strips have at least 4 pins. Please, don't do what I did. They don't work, and they are a major inconvenience. Thank god for Amazon's return policy.

These connectors worked great with the LED lights I was installing.

Says it comes with a manual and adhesive, but neither of those were included.

These connectors work great. Just cut your LED's at the proper spot, trim off any plastic that might obstruct connection insert and clamp down. They do not inhibit any brightness to your LED's. Great value for the price.
