  5. Lakisha Mullenix

    Product identical to AD. The app watch is compatible with iPhone ios13. Is compatible with Android also. Battery life very good especially if stand-by.

  6. Branda Goshorn

    The watch does not work!!!!! The seller does not want to refund. I find it with the BLUETHOOT and after IMPOSSIBLE to connect it to the app I tried with two phones and two different apps. I put 5 stars just for it to go back. Thief!!!!

  8. Aamir Boyd

    Loved, came very well packed, meets all specifications. Arrived in 15 days in Brasil and took over 3 to get my home in Paraná… IS super beautiful! Will test the battery and put additional comment.

  9. Thibault Silvestre

    Came in perfect condition, very good

  10. Aliya Fernandez

    The watch is beautiful, the true picture. The shipping was fast, but, because the corona virus delivery took.

  11. Emmanuel Gillie

    Loved this watch, super simple but is promised.

  12. Sarina Santos

    I ordered 4 pieces, without a box. all packed well, the clock was 35 days. all watches came to half the charge, the norms are kept in standby mode. the Pulse and pressure measures to me seems to boom, sometimes falls. vodac SMS come, you can read completely. calls Also displays, all with vibration! pedometer is also relative. I have this first smart watch-I recommend for this price! the photo looks big, in fact not big at all, on the man’s hand would take the screen more. take the norm thing!

  13. Alisa Watts

    The clock is good, everything works, but the herobandiii app does not connect, in the instructions of another application and it frankly speaking shit, but alerts work, SMS, calls, wats, I took it for that. Maybe someone had such a problem with the connection. The clock because of this in English, but Russian notifications.

  14. Franchesca Schwebach

    A month in the Altai territory. Came with a charge of 52 percent. On the hand do not seem big.

  15. Aasiyah Haney

    The clock ordered on March 27 came on May 6 to the Irkutsk region,. very long through the mail of Finland. The watch as in the picture, they measure certainly not exactly, but at least you can navigate. came completely discharged. Of course I expected more, but for my price will go. The app saw the clock, mostly it is necessary to navigate through the application, not through the clock itself. Viber message and VKontakte does not highlight very sad, only face book and WhatsApp, twitter and other little known messengers and everything. At least the usual text shows.

  16. Takako Ream

    Additives in Korean alphabet manual for the instrument interlocking heard some force used to work very well. Phone letter card stock Korean alphabet support is very well. Reminder in other settings would cafe posted gloss and charg charge percent keep up to alert.

  17. Della Drew

    On the first impressions-a very cool clock. Comfortably sit on the hand, light, seemingly pleasant, large screen, many different dials with the ability to set your picture. There is a Russian language in both hours and in the application and even in the instructions. The first pulse and pressure measurements are quite accurate, there is a pulse measurement function throughout the day. Weather and message shows. I will test the pedometer, how much charge is held and other measurements. I took two pieces without a box-everything is whole and works. To Chelyabinsk drove 37 days.

  18. Durante Sciara

    Hours of norms for this price. but very dim screen in sunny weather is not visible. brightness for all.

  19. Lluciano Marcos

    The measurement of pressure with large errors, it upset, and otherwise the functional is good, the seller is good, honest, for this five

  20. Jaimee Harter

    Ordered on March 27, received April 16. The track was tracked, packed was just in a bag, by this package was worn out. But inside, everything works. Readings are roughly the same, difference 2-4 units, but you need to keep your body calm during the measurement. If you swing and shake your hand, then the readings will be in dozens of units.
