Came in nine days! The header sockets look good and are well manufactured. The pins as usual for Chinese headers are thin at 0.6mm instead of the usual 0.8mm-0.9mm but I've grown fond of that, if you've ever had to unsolder and remove headers, the 0.6mm pins in the usual 0.9mm holes makes it much easier! Internally, the clamping springs on the female headers are also thinner (yes, I dissected one), but it turns out it allows for more insertions before failure! Sometimes cheap manufacturing can pay off in strange ways.
