I've had really bad luck with these watches. My first one would freeze, siri wouldn't work, and no apps would work. I exchanged it for another one after spending 1.5 hours on the phone with support. Then 9 days later the battery died on my second one. It wouldn't charge despite being on the charger over night. It would have about 60% battery left and it would be completely dead in the morning. After this happening 3 nights in a row the battery finally wouldn't charge at all. Now I am on my 3rd watch. Hopefully 3 times a charm. If not then I'm returning it and waiting for the second generation models.
