I use the cable bridges when tinkering with the Arduino to the breadboard and for that they are exactly right.
About the 2 1/2 weeks for delivery from door to door, I encourage me not to, especially since this may be due to both the senders in Hong Kong, as well as to the customs clearance in Frankfurt.
So why only 4 out of 5 stars? Well, with me in the cable female / female is (female / female) arrived. However, the accompanying delivery note to match. For the price I order anyway and start fresh. :-)
