My husband brought Apple iphone 5s couple of years back and its working condition is awesome. till now we never had any problems with that and we never spend any money for repairs. Me and my husband exchange our phones very frequently. I prefer to carry 5s series only as its very comfortable and compatible. Style and look wise is wonderful and I feel very proud when the other people watch the phone brand logo. its available in 2 colors and we took black color as me and my husband love that color a lot. its a bit difficult to understad for Layman when comparatively other brands. I dont have any words to explain about the sound system. its simply superb, you can enjoy each and every beat of song when you hear with head phones. cost wise its bit high but we can spent that much for worth products.
