... I was confused, I then checked for safety's sake if this short circuit described in the "1-star review" is present, the is not so. My product is flawless and perfect fulfilled his service, I am very happy because I now have an adapter for almost all balancer, positive is that even a solder joint is free and you can optionally add there a nonexistent connection, of course, caution offered, but that is also in the accompanying description.
So from me a strong buy recommendation, deserved 5 star :-)
