iXCC Lightning Cable 3ft, iPhone charger, for iPhone X, 8, 8 Plus, 7, 7 Plus, 6s, 6s Plus, 6, 6 Plus, SE 5s 5c 5, iPad Air 2 Pro, iPad mini 2 3 4, iPad 4th Gen [Apple MFi Certified](Black and White)
I've had this for about a month now, using the cables both in my car and at home.  They are thicker than other cables and the plug seems more solid and larger than typical lightning plugs.  They fit my iPhone 6+ well.  I have no problems so far.
