Less than 5 including postage (free) you can ask for the moon ... First of all I thought that contacts were white metal as the pictures they are yellow. I rechecked under proper lighting and I realized that they are yellow but to me it appears paler than the ones I had seen so far? ... If these seem rj45 quality while acceptable and in any case, like all rjxx they are not really made for connecting / disconnecting constantly, otherwise better to choose another technology (wi-fi, Bluetooth, switch, etc ...). For the price (which makes the wait is acceptable, especially with free port from China) I am perfectly satisfied. Simply, simply to go in advance after all, right?
