Haven't had a chance to use them yet.
I can't yet comment on the durability of this product, but it worked perfectly the first time and every time after.
These wires were just what I needed for an experiment to se if I could run a small relay from the 5 volts at the USB port. The relay didn't work but the wires played just the part I needed them two!
