They come in 2-packs for a reason.

10 minutes after opening my package this coupler snapped off in the cable I'd also just received. That buggered my cable until I could chisel this brittle coupler out of the cable end. I'll give it 2 stars since it should work if you're dainty and it's 45 cents, but PCH, I hope you'll source something with better quality, even if it costs a whole dollar.
ConsBrittle, cheap and expensive in time wasted when it breaks.
