Hidrate Spark Smart Water bottles with sensors

Hidrate spark waterbottles with sensors. Set your personalized water goal through the mobile app based on certain questions and drink! Challenge friends and family near and far to hit your goals!!! We used these with family back home to hit our goals but we just don’t use them anymore. Simple as sync, fill, and drink -it auto syncs and tracks water real time-every sip. All 3 work, may need new batteries. I will consider any reasonable offer!
