The band should be worn loosely.
We recommend charging your Flex every few days to ensure you are always tracking.
Flex has been tested up to 1 ATM meaning it is sweat, rain and splash proof. However, the device is not swim proof. We also recommend taking Flex off before showering because, as with any wearable device, it’s best for your skin if the band stays dry and clean.
If the band gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Clean the band with a mild soap-free cleanser like Cetaphil Gentle Skin Cleanser or Aquanil. Give your wrist a rest by taking the band off every now and then.
The wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Flex also has a surgical-grade stainless steel clasp.
Flex syncs automatically and wirelessly to tablets, computers using Bluetooth 4.0 wireless technology.
