Worked great. Far more affordable than the name-brand at the auto-parts store. I desperately needed these when I had to replace a fuel level sensor on a nearly full gas tank in my 2004 expedition. It almost felt like cheating to unhook a fuel line, and use these and the fuel pump to pump the gas into several cans.

I've only used one of these one time, but it worked perfectly. Very handy.You could do the same thing with jumper wires, etc., but this is so much quicker and easier.

I love these things. Easily test a circuit to make sure everything is functioning properly with complete control. Excellent product!

I only needed one in this set, but it helped me track down the issue I was trying to fix.
