The build quality was really very bad. For the male connector it was ok, but the female was not usable: It fell in piece during soldering. In addition, the vast majority of female connectors are responsible for short circuits, whether they are already soldered or not. Finally, from an aesthetic point of view, male and female connectors are not centered (co-axial) once they are plugged in, once again due to the female connector (a wire in it is pushing the male connector to one side). To conclude, it's a very very bad product quality which might lead to a big loss of money due to the short circuit (in my case 8 rechargeable batteries - about 80€)
Item arrived, all good, many thanks.
