Fulfilled its task

It's a simple diode. Delivers what it promises.
Do not expect too much. Price for but ok.
Cable could be a bit more flexible and longer.
It would be nice also if the + LED and the LED would have different colors.
Still can work with it without any problems. Well suited for fast "Come-What-to-or-no" questions in the automotive sector or security testing without the hassle of removing.
