After 3 weeks of use I can write a specific comment. In operation after access to the Sony site to download and Lifelog smart connect. Pedometer functions, running, walking, sleep well but refining. for calories I do not comment. My phone is a Samsung Note 2 and all the functions are not available with another sony device. With Lifelog you can set daily goals. Report Summary: performance day, week, month year The battery takes only 3 days to be announced 5 days, but can be recharged in 30 minutes. When the battery is low counts become fanciful. This is the weak point that makes me afraid for the life of the product. The quality of the bracelet is correct, pleasant to wear. But I expected more in terms of robustness for the price. It is waterproof to shower or splash-type dishes, but do not expect to swim! Amazon perfect service as usual.
