I am using I phone 6. It is a very good phone. Apple product provides you with all the basic amemities whic you always want in your smart phone. Performance wise it is a nice product. It is very fast while using it. Camera quality for primary and secondory camera is very much appreciable. This product provides you a different world of smart phone. I will suggest you to buy in space black colour. The screen is 4.5inch. Some rumors arw that all the apps are paid in apple store. but believe me all the neccessary apps are easily available free of cost. so in my opinion its really a good product from apple. and you will love to use it
