JACKYLED T Shape 4-Pin LED Connectors 10-Pack 10mm Wide Unwired Solderless Gapless Adapter Connectors Terminal Extension 12V 72W with 32pcs Clips for 5050 3528 SMD RGB LED Strip Lights

I got the “T” version and they work exactly like they are supposed to. First, the “T” worked perfectly for my under cabinet lights where I wanted two rows of light - one near the front edge and another near the middle of the cabinet. The clips that came with the “T’s” were also easy to use where I just lined up the light strip and slid it in and locked the clip. Wish I had purchased the “L” from this company as the other I tried worked about 1/2 the time and sliding the strip in those clips were very hard since they were poorly made. Instructions were very clear but it’s pretty simple to use the item. Lights work just like I wanted them to. Wish I had purchased all the connectors from this company.

My son was very happy with the quality and size, but the connection parts were a bit scary and not to user friendly

I tried to put this together in one sitting and I became extremely frustrated. I attempted to finished the next day and took my time this time, making sure to really INSERT the led light ENDS as much as possible into the connectors. This really helped and they actually lit up without being so finicky. They do NOT close though, about half of them closed without a problem and the rest I used pliers and the plastic caps still didn’t lock closed. I left them open and I’m hopeful nothing occurs because of this. I cut the 100 ft long LED lights about 5-6 times to get the result I needed, connecting using the T-connection. I am satisfied with the result, with fingers aching.

I was looking for a way to split a 16 foot RGB LED strip so that I could run power to it from the middle and install an RGB LED into some new custom cabinetry (the top shelf in the attached photo). I purchased this product, but after it arrived, I realized that it wasn't going to work for that particular application. The main reason why it didn't work for me is because of the size of the T joint in this connection. But I want to stress that this product can fulfill a need for most people, and in the end, I used these connectors for another purpose. The only reason why I didn't use this product for that top shelf was that the bookshelf was a permanent installation and the location where this T connector would have been installed would not have been accessible without significant effort. These aren't something that you can just tuck in between a shelf and the edge of the cabinet. In fact, after I bent several of these, they tore, which broke the connections. Instead, for the top cabinet, I soldered individual connections to each side of the wire and brought those wires down the wall behind the other cabinets. All of the wires pool together are are grouped below the desk in this photo (pull the chair out and we have a shelf where cords come out and transformers are plugged in). As it turns out, I was able to use these connectors in that spot, because I now had the two wires and felt more comfortable using these connectors where I can get at them and make fixes if needed. But I would just stress that I wouldn't really consider this as an option if you are planning to place this connector somewhere permanent that isn't going to be easily accessible. These connectors are kind of finicky and as you jiggle them the connections are lost. They are a lifesaver in that they make it easy to quickly get connections tested, but I'm already planning a custom board for all of my connections to replace these. TL;DR: In a pinch, or even for testing what you are planning to install, for the price, these are invaluable. Just don't plan on installing these on a job for hire. These aren't permanent-grade connectors.

I had about a 12" piece of a light strip that burned up and I was able to cut out the piece and replace it with a new piece using the connectors. It worked perfectly the first try.

As an electrician of 40 years,WHY IN THE HELL ARE THE POSITIVES REVERSED ON THESE???? I needed T-connectors,NOT a nightmare! You should just be able to tape as you go,cut,add the junction,and move on. However,one side of these craps is completely opposite of the other,and will NOT WORK. I wasted 2 freeking hours before I realized I had to pull down what I already put up and reverse the next freeking strip. So I ripped paint off cabinets,wasted 2 rolls of 3M tape,got a SEVERE headache,and wasted 4 hours on a 1 hour job. Whatever directions these guys give you are so screwed up and WRONG. Heres a quick electric lesson. + goes to PLUS. RGB go to RGB. What happens when the next guy has to troubleshoot? TOTAL CRAP-I should charge these people for my wasted labor time. ATLEAST change your listing to REVERSING T CONNECTORS.

I purchased these connectors to create a light display on the outside of my home with LED light strips. I have not mounted the strips, yet so cannot verify the quality of these connectors at this time. They appear to be high quality and I believe they will do the job for me. I will update my review if needed after using the product.

Very nice connector to join LED strips into any configuration. Smartly thought out product. One of the sockets was missing a joining pin but no harm since I did not use all of them. No need to remove a star since they work so well.

Overall ok and works. A few of the connectors were Missing the metallic connectors making them nonuseable.

Useful

Good quality and fast deliver

I bought 32pcs Clips but there were only 30 .

Worked great. Slim fit.
