This Hicon jack is very resistant and well built! Solderability is perfect and the construction is bulletproof! Bought a few of these jacks to make guitar cables to plug in pedal boards, because of their very strong construction: frequently there comes someone that steps on the pedalboard connections and ruins a jack, but with these Hicon jacks that doesn't happen, they are very resistant. Step on them, pull them, abuse them, they will witstand!
