I am using it since last 6 months.
Comfortable look with comfortable to use & carry.I love space gray.
Having 16gb in build , 1gb RAM like 3gb of Android phone RAM.
Great feature , with comfotable handling & classy look.
Sound enhancement is best in iPhone 5s .
Additional features I like is that figure print touch lock & security services in iPhone .
No lagging & no hanging I ever found .it’s totally value of money in all range of iPhone .
Reliability & durability has no doubt , as this is iPhone .
