Firstly, I wasn't expecting much with this for the price.. And left it a few days before opening. But I was shocked at how robust this thing is. The cable is like a hard mesh which seems indistructable. The ends are solid and have a metal feel to them. The actual end caps are fantastic!! My previous cable (Samsung original) always seemed to catch the port on the inside which was irritating. This fits snug and seems incredibly well made. We'll, those are my first impressions, so will update if anything changes. Oh, and it does fast charge!
