Bought it to replace a regular low quality stereo jack on my Fishman Loudbox footswitch. VERY sturdy, the amount of anti-strain and protection built into this is beautiful - a plastic casing inside to protect the wiring, a rubber cable cap that lightens any tugs of the cable from the jack, the slide lock 2-piece jack construction... it's brilliant. Much better than all the alternatives (Amphenol, Hicon) I've used thus far.
