Pretty much the only Apple cables I like are the iMac power cable and the macbook charger extender cable. Their USB-C cable seems thicker, so maybe they're making a bit of progress there.
I think it frayed a couple years ago so I taped it with electrical tape and then it just became worse over time. I didn't look at it too much because my macbook just sits in one place most of the time nowadays, but now I'm taking a look at it and there's blue stuff under the tape. I may need to get a new one.
Out of the ones in the custom search, I'd say steer clear of any cheap Rosewill cases, they're awful to work in and feel cheap. But I agree with Archie on the MasterBox series, they're pretty skookum.
