Some pros: Bought two bracelets. There were no issues with the connection, because. before that there was a similar bracelet of the 5th generation (it did not break, went on an independent voyage in the Black Sea). In terms of reliability and water security, there are no questions. Its cons: On one of the bracelets, the duration of sleep is not determined. Resetting to factory settings does not help. If you accidentally long press on the screen, the screen editing function crashes. Oxygenation is read crookedly.
