This smart zikr ring has a basic waterproof function, which can prevent a small amount of water splash in daily life, but it is not recommended to wear it for swimming or bathing.

Five sizes of finger ring adjusters are included in the product package, which can be changed according to the finger size. Simply gently pull the original finger ring adjuster and replace it.

Regular calibration is not required, the precise direction data will be automatically synchronized after Bluetooth connection to the app.
