Fragile, extremely fragile and doesn't need to do what it's designed to do. Ordered these for my 8 pin 3X GPU jumper. You appear to be thin. Each wire insertion causes the next spot to bend flat. Have a small tool or flat head handy to *neatly* reposition the clamps. Cable combs are a lot better for the money, but I wanted them right away. Sorry for my impatience.
