I like these uxcell alligator clips as a more durable version of the cheap ones I've used. I bought these to make some handy two wire inputs from my power supply for various uses to power my projects. They were small and not good enough to be used more than a few times and then the loop wouldn't hold and they exploded when the hinge pin broke free and came out the widened end. They are better processed and therefore more expensive. I really like her.
