I liked the features provided by the phone and the fact that it was shock proof and water resistant (without a case) made it my choice. However after 5 months (never dropped) the glass on the back cracked. In calling support - they wanted to use my extended warranty to provide a new phone - I was then transferred to warranty claims (because I did not feel this was right) I have been waiting now for more than a week to receive information on sending the phone in. I will now have to call once again.
Unlocked At&t LTE banded phone is fast, and powerful. It runs all my apps, all my email, on a huge, bright, beautiful screen, and it does it for two days straight. That part is really true, you can easily get two days out of your phone, 3 or more if all you do is occasionally talk. This is my first unlocked phone, and I will never look back. The Sony apps all work wonderfully, and integrate with my other Sony devices very simply. I am an IT professional, and use my phone often, would recommend it to anyone.
