I had the smartwatch 1, I am not disappointed with this one. it has all the functions that are indispensable to me and then some. 1. I do not magnifier my calls when I do not hear my ringtone. 2. I know at a glance the contents of my e-mails or SMS. Here, cétait for the most important, but there are also apps to manage music, to monitor social networks ... And for me, it is useless to take pictures with poor quality then shows that we have the handy phone for that. well, try to follow a telephone conversation on your watch and you will quickly cramp good (not to mention stupid). These are two missing features that make this watch for me the best shows currently on the market. Cons: I wish an induction charging (it would have to have a completely waterproof case), better battery life (but charging is not so restrictive that) and shows a bit more solid (j ' there'm careful, but it seems a little fragile). So I noted 4 stars for rent effort that Sony did for his last show. But it does not mean free of defects.
