So far I am very happy with everything I ordered. The smart watches I have used in the past and most recently the samsung galaxy 5, has the worst battery life ever. My watch had to go back on the charger every day and a half. The carbinox I bought has lasted 8 days and still has 36% right now as I am typing this. It does everything the galaxy watch did and more but lasts a lot longer! I wish it was offered in a smaller size but I am ok with that trade.
