I received the phone on 15 October 2015, I ordered this phone for my cousin and believe me this is great phone with very good build quality. Mine is 16GB version.
This is future proof mobile phone like other Motorola phones. You can use this phone at least for 2 years without any issue. And also Motorolla has wide network of service centres.

1) Descent Camera, better than 2nd Gen and 1st Gen
2) Waterproof design
3) Good Battery life
4) Good Build quality
CONS-
1) Heating issue with Gaming and sometimes with Normal Usage
