The HidrateSpark PRO Smart Water Bottle is the world's smartest water bottle! Stainless Steel vacuum-insulated body keeps drinks cold for up to 24 hours, prevents sweating and allows for a pure water taste. Both variations of lids feature a protective spout cover. The Chug lid includes a button lock to prevent accidental spills. This 100% BPA-free bottle includes an easily accessible rechargeable battery on the bottom of the bottle with a fast charging cable so your bottle can always stay charged while you're on-the-go. This new design also includes an improved sensor technology with clinically proven accuracy within 3% of manual readings through Mayo Clinic trials. Using a built-in sensor, the HidrateSpark PRO bottle tracks your water intake and syncs via Bluetooth to the brand’s FREE hydration app on your phone (available on iOS and Android). When a user falls behind on their hydration goal, LED lights embedded in the sensor puck glow in customizable patterns as a reminder to stay on track. Users also receive reminder notifications throughout the day via the hydration app. Perfect as a gift for friends and family—track each other's progress and make staying hydrated a fun activity!
