I just had this watch for 3 days and I'm delighted. I bought it on a whim. I had dinner with someone who had it and as soon as I got home, I bought it on the Internet. I thought it would be a purchase gadget but it does not matter, we must know whether pleasure. And finally, although it's still gadget, there are useful things. For example, appointments that are automatically displayed on the calendar, notifications FaceBook, SMS, email, calls with the caller's number ... You may say that it is useless because it was the phone for that and it is not wrong. But today, my phone was silent and my watch, I would have missed an important call. Applications such as the calculator or voice note-taking or sending email or SMS voice recognition are also not bad. I also like the ability to ring his phone when it was lost or BitDefender informs me "Do not forget your phone" when I away from it. Stuff to count my steps and my heart rate, I do not use them. I have yet to test Google Maps for the watch tells me my route but I think it's not bad. Apparently the watch vibrates when I have to turn left or right. The Camera function to trigger pictures from the shows on his phone gadget but entertains children. The stopwatch can be handy. That said, my favorite app is Watchmaker Premium. Buy 1 and some on the Google Store, this app lets you customize wish to display. Add characters or pictures on the screen information such as upcoming appointments (very handy at work), the weather, the battery, the current date but brace yourself: time !!! top too. I had a problem (hence 4 stars) because the watch could no longer cling to my Bluetooth connection S3. I had to do a factory reset of the watch and everything is back to normal. Furthermore, I still have not found as to prolong the lighting of the watch longer. She goes to sleep too quickly (but it must be because I have not yet discovered). Finally, it had been years that I was using more shows (I had time on my phone). I learn to reuse this bracelet on my wrist with another use, just as nice. As long as I put the wallpaper Breitling and here is the class :)
