In my experience buying used iPhones is a minefield. The main problems with the 5 is obviously the screen and battery. For how much the new ones cost I'd recommend buying a new one from a store with warranty because if you get a dodgy used one the cost keeping it working well will soon outweigh the cost of a new one.
My wife and daughter have iPhone 5's and they've both been problematic.
Thanks hedgy73
I chose to follow your advice, I will go to the store and buy a new one.
Thank you to all who showed interest and made offers.
