  15. A***v

    The opening hours were turned on and the charge left 2 strips. If you consider that they went to Sochi for a Week 2 and another month in sdek. They sent SMS, sdek, 2 days before the end of the storage period, just fucked up. The clock itself is pretty. I ordered a girl 16 years old. She liked it.

    Just arrived, well packed, nor the crumpled. Still not used, but comes in Portuguese. THE size was great for my arm thin. Hope use soon and try and be really Q imagine.

  32. I***n

    Everything would be fine, but automatically measures only the pulse, other parameters on request. Went a month, came in a box, as ordered. New, by the way, yes. The only jamb-when the minyushek flips sometimes jumps the weather

    Good I noted all during the request and this there, so far have nothing to complain of watches only delivery that took thought, but how come all correct worth the wait, I bought three watches and all came in perfect condition and not taxed, My biggest fear was about chargers saw enough people complaining that came the wrong 3 pins but my all came right 2 pins and working, who does not know the watch is the HeroBand? application, Am using only 1 day when spend more time use back here and say what am thinking, yet am loving. 27/10 was made the request 01/11 was sent 19/11 received in mail Brasil 26/11 was released by customs 27/11 was sent to Floodplain Big 03/12 was sent to PVA 06/12 arrived 15/11 was the deadline 40 days in total the watch was purchased 36 days calendar that is coming

  37. I***a

    Cool watch! Came quickly, Connecticut with an iPhone at once, all notifications except VC come, the bracelet is only uncomfortable, but probably it’s a matter of habit. Let’s see how they behave further.

  38. E***k

    Good hours for such a price. Of the minuses: they are uncomfortable to sleep, because the screen turns on from contact with bed linen and the clock is sometimes vibrated. It was not possible to install your picture on the display or download another widget. The application hangs by 20% maximum.
