Cheap, which is good, but you get pins that bend easily and are slightly smaller than normal pins, so standard Dupont jumpers will not fit. do not fit closely to them (this is not the case when a set of headers is small - all 5 exhibit this behavior). The connector itself stays in place, but when connecting/disconnecting individual wires in a prototyping scenario, watch out for loose connections. Otherwise good, tall plugs and each has 3 removable spacers.
