To be honest this is my first iPhone. I had always wished for one and its really as good as I had heard of it. I ordered it online one month back and using it since then and till now I didn’t had any problem with the product and it is durable as well. I am writing pros and cons of the product.
Pros:
Two cameras are better than one for fancy portrait shots and optical zoom
A 5.5-inch screen gives you tons of space to view and tap
Water-resistant
256GB option for monster storage space
Longer-lasting battery than iPhone 6S Plus
Cons:
Most expensive iPhone
Large if you’re used to a 5-inch screen or smaller
No headphone jack!(You have to use the Lightning port or wireless headphones/speakers)
Static home button feels weird at first
Lastly I would say that if it is in your budged you should definitely go for it.
