I ordered this for my new S5. The charger and cable was delivered very promptly. As stated, it's a official Samsung product, so the quality and build is MUCH better than the cheaper chargers around.
The charger itself is very compact, as the earth pin slides down into the body of the plug - so great for travelling and for using around the house.
I did have a problem with the cable provided - there must have been a small manufacturing fault so that I had to be very forcefully to remove the cable from the phone once attached....I was concerned that this would damage the micro USB port on the phone - and replacing the micro USB port on a S5 is no easy thing.
I contacted the seller and a replacement cable was sent immediately - the new replacement cable works a treat.
Great product, very good seller - I would recommend highly
