Bests & Worsts Reviews from Amazon

This cable failed at the one year mark, so why am I giving it 5 stars? I used this cable as my everyday cell phone charging cable, which should tell you that it took a lot of flexing and bending. As an engineering student, I was curious about what was inside. After the failure I performed a teardown to find the point of failure and determine how well the cable was made. Overall this cable was engineered ridiculously well. The point of failure was the negative power wire and it was due to excessive flexing. The heavy gauge tinned copper wire was 7-strand. I think a more finely stranded wire for the power wires would have increased its life. Everything was heavily shielded and all wire was stranded tinned copper. The power wires were a very large gauge (no smaller than 21g). All data lines were twisted pair in individually shielded pairs with a stranded line for reinforcement. The terminals had shielded covers that were soldered to the shielding braid from the cable. I could go on. The point I'm trying to make is these are wonderful cables for a professional environment that should last forever providing there is minimal flexing in its daily use.
