I just upgraded my Galaxy S6 to a Galaxy S9. I bought these adapters so I can continue to use my existing micro USB cables to charge my new S9. I tested all four adapters and they worked great. The fit was good and comfortable. I noticed that another reviewer said that "Fast Charge" is not compatible with his S9, but as you can see in my screenshots it works. I'm currently using the original Samsung Adaptive Fast Charging Wall Charger with a regular 10" micro USB cable. (He may not have used a wall charger or quick charge connector.)
