I don't have issues believing that, but I still kinda need an ELI5 of why micro is more durable. The accepted answer on SO briefly addresses it but I'm not really any wiser, maybe in part because I'm not a native speaker.
For the mini, the wobbly springy bits are in the device, for the micro the wobbly springy bits are in the cable. The cable is cheaper and easier to replace. The springy bits bend out of shape over time and fail.
