Y’all! I LOVE my new Hidrate Spark 2.0 Water Bottle. I have been suffering from low energy, headaches, and just pure dehydration. This water bottle has basically cured all of those symptoms. My husband bought this for me as an early Christmas present and I must say its his best purchase yet! This water bottle reminds me throughout the day to drink water and will blink a light at me as a stimulus/reminder. It also tracks my progress on the app on my phone. It also tells me how much water I should be drinking for my height and weight. Its pretty cool! If you do not know what to get you significant other, friend, family member, or yourself for christmas, get this Hidrate Spark 2.0 water bottle. I guarantee it will change the way you drink water. It will also change your life!
