Query: Poor design, should be recalled

It's a terrible design. Obviously the rubber sleave near the plastic magnet was meant to prevent wires from breaking, but it's clearly not good enough. We got about a year out of ours before it started going bad, and now it's just junk. I'm an electrical engineer, so I thought I would just pull it apart and splice the bad wire out, but this thing's clearly designed to never be opened and broke into several pieces when I slowly pried it out. Why would any real engineer ever design it like that? It makes repair a waste of money and time. I'll try retrofitting an extra long hardened sleave over the connector to prevent this on my next one.
