This is the best G-Shock I have ever owned. Casio keeps adding features while keeping them rugged and stylish. Connecting with the phone App is flawless and programming your preferences is easy. Calibrating steps and distance and setting up text=email mail is a bit limited but it works.

Great watch, got software update on the first connect to mobile phone. Very accurate parameters.

Trouble updating to the phone call software.
