This product (6ft & 10ft MicroUSB to USB Cable) replaces the original cable that came with your phone. The microUSB connector design includes two small protrusions that provide a strong and secure connection to the phone that is far superior to the original which has a fragile design that wobbles when plugged into the phone port. With the original cable, fast charging often became standard charging again, and connecting the phone to a computer to transfer photos was often lost altogether. Both problems are solved by the new cables and we are very satisfied. Highly recommended!
