Worn for about 2 months. I use the 3 foot cable at work and the other two at home. They are all associated with OEM Samsung PD chargers, so I can only comment on the quality/charge time for this model of device. Charges as fast as the thin cable that comes with Samsung. The neck of the cable (wear corresponds to the plug) is strong. I folded them up, threw them on the carpet and rolled them up to put them in my backpack or locker and they still held tight. Use them all daily except for the 3ft cord which is used 4 times a week. I have used data cable to the laptop and it seems fine. If I ever need a replacement, I will definitely use them again.
