Poor quality product should not be sold without that one is checking the conformity of the product, for example: j 'have order 2 I have had the good idea to have tried it in the female connectors before soldering and I realized that they did not fit properly in it, the 2 connectors "force" not like ... so when I tried to remove it, some got stuck in the house ( it took me to open my camera ... Grrr ""@@!!!!!! ...) is the m ****. If we look closer at with a magnifying glass it would seem that the finish pole diameters are not compliant. I ordered 2 more in Mexxtronic there are metal is more expensive with a 15 day period, if it is the same I would order via CONRAD rather q'AMAZON ...
