Ome of the biggest achivements by apple was iPhone 5s. It has looks, good processing and ram management and smooth optimized ios.
Camera is one of the best a mobile can have. Having an iDevice at a low price point is also a great thing.
Some of cons are, low level speaker, it has become obsolete and the screen size. If you want experience and iDevice for the first time at low incl vestment go for it.
