The teeth aren't strong enough to pierce the casing around the wires, so they don't make contact. Using pliers to add a bit of pressure does nothing, as the amount of pressure needed to pierce the wires only cracks the housing.

These things are amazing. I bought them to split my cords and have 2 short ones on our church stage. They work very well and we're easy to setup. Its only been a week. Will update if anything goes wrong.

Work as they should. Easy to use.

I make a lot of LED projects and constantly look for ways to conveniently connect power to a strip. Soldering works, but is often difficult to get right due to the coating on the strips, the thin layer of copper conductor and nature of the solder in use. These do offer quick connection to power and controllers, but still need some TLC to work properly. AND they are not at all suitable for anything that will be moved, vibrated or shifted. The connectors that attach to the copper strip work, but the flexible plastic case permits the strip to move which can break the physical connection to the tiny copper pads. I find it desirable to scrape the surface of the pads on the LED strip lightly to improve contact. These connectors do work consistently and are great for static connections that remain rigid once connected. The cost is very reasonable for prewired connectors.

For the les side, the end that meets up with this will need almost a whole pad- do not cut in center. Not sure how strong these are in regards to maintaining connectivity. Seems that a little mech. movement at that joint would compromise power. On the one I used, it seems tight.
