BTF-LIGHTING FCOB COB 8mm 0.31in Connector Kit 14pcs Transparent Connector 5pcs 15cm Long 20AWG Extension Wires for Non-Wired Gapless Solderless,FCOB 2 pin v+ v- Single Color Strip Corner Connection

Super handy and saved lots of time soldering.

Worked perfect on the COB extras I had laying around.

Products work great. They're customer service is also impeccable.

They're great when they work but you have no idea if the connection will actually work until you compress them. If the connection fails, then the copper tab on the light strip is ruined and so is that connector. Then you have to shorten your light section and try another copper connection point. Very frustrating!! However, if the connection IS successful, its a huge time saver over soldering and a more reliable connection than soldering. I wish there was a way to verify the connection was good before you compress them but I don't see how that can be possible.

They're very simple, but they work very well.

I used the 8mm, 2-connector version to connect COB LED strips from Home Depot. The original Home Depot kit came with a power supply, a lot of wire, including a Y-connector, but by itself was not adequate for a fairly small under-cabinet lighting project, because it didn't provide a way to make connections over short spaces. One issue I had was that I needed to put some of the lights on the bottom of an under-cabinet radio (remember those?), and with the original kit alone it was impossible to do that neatly.With these connectors I was able to cut the original strips *and* the wiring, and make new connections anywhere I needed them. I was even able to cut the pins off the end of the COB strips and insert the short stub with the pins into one of these connectors to make a new male or female pin connector on the end of a wire. The original 20 AWG wire also fitted into the connector, so I didn't need to use the wire that came with the kit - I have that for a future project.I had no problems making the connections - I used needle-nose pliers, so had to come in at an angle, but it probably would have been fine if I'd used a smallish pair of regular flat-end pliers. Every connection worked first time, and I had no damage.It took me a while to figure out which of the many kits available on Amazon was the right one for my project, but I'm very happy with this choice.

This review is less of a critique of this specific product (which I purchased) and more of the design of all products of this type. I bought the correct size connector for my light strips. They installed perfectly without issue or difficulty. The lights lit up, so I know I installed them correctly. I used them to connect 4 strips via 3 connections.However, almost immediately I noticed that the further down the chain, the dimmer the lights became. And then they started flickering. If you wiggled the wire, they'd just go out. The design is flawed. The surface area of contact on those little staples is just not large enough. I ultimately removed every last one of these clips and threw them in the trash. I went back and soldered the joints to the wires instead, and now the lights work perfectly.

These things are fine for connecting two strips together directly, but note that they are actually vampire taps, not crimp connectors. That means they only work properly with EXACTLY the wire they were made to work with. So you really do need those included bits of wire or you’re going to have problems.Not only do they need stranded rather than solid wire, but if the total diameter with insulation of the wire is not exactly right then the vampire teeth can miss the wire or not hold it properly. So don’t use with any wire except the little bits they included.Basically these are only good for 1) connecting two strips directly to lengthen a strip or 2) cutting and reconnecting a strip with the included bits of wire so you can turn a corner. Otherwise, DO NOT USE.If you need to connect a power supply wire for example then you’re going to need to solder it. DO NOT USE these for that. If you need wire between two strips that’s longer than what they include then you’ll have to solder it. DO NOT USE with any wire except what fits exactly.I’d probably rate this higher if the instructions did a better job of clarifying these major issues.
