I ordered you to my cable Development Boards (AVR / ARM / FPGA) to each other and to connect with breadboards. After I've ever seen at cheap alligator clips a resistance of 2 ohms, I first checked the line resistance. The multimeter has fluctuated 12:00 to 00:01 ohms, which means that the line resistance is definitely under 0:02 Ohm and the cable actually contain copper. The crimp contacts are all properly connected to the cables and thus not objectionable. From the strong smell of the box, from the report some buyers, I could not find anything. It smells just easy for new cables, nothing else. In any case, I recommend buying if you have enough time and patience, as delivery is made directly from China and thus can take up to 3 weeks.
