Nice phone, and if you like small screens, the iPhone SE has the 6s guts in a 4.0" body.
Now why do I mention this, why talk about the iPhone SE when the iPhone 6s is so good?
Because the iPhone SE is almost always so damn cheap. Like I can walk in a store in the US and get it for $200 with no contract. Though it would be $400 for an "unlocked" model from the apple store that works with all carriers.
Personally though I think the phone is too small. My mom loves her iPhone SE, though she probably would have went for the 4.7" iphone 6s that you have Mookie with hindsight. She did not want a big phone, but she may want something a little bigger next time.
