My wife's Samsung A5 2017 charger had blown so we needed one urgently having family members ill. Ordered one from UKMS on Sunday morning (27th Sept) with delivery by Amazon Prime. Charger arrived Monday afternoon. Charger brand new and works fine. Very pleased. (Two things on their website need tweeking. Firstly the delivery option for Amazon Prime only shows as an option when you are finalising the order. Secondly, the link on the e-mail telling me the goods had been despatched took me to Star Tracking in Australia !! However, at the end of the day I received the charger in good order at the time specified).
