The quality of this lightning cable is really top-notch. The cable is designed to withstand a lot of use and abuse, and is much more durable than the standard issue Apple cable.
I found the charge time on the cable to be very fast. The connection to the phone is solid and strong, and there’s no slipping in the port once the cable is connected. I’ve used it both connected to a USB wall charger and in a car charger, and both have given me fast charge times for my iPhone 6.
