This is a great bottle for reminding you to drink and refill through the day. Love it!
Word of caution. Have found that air pressure changes like flying or driving in mountains affects bottle and will cause water to shoot out of straw when lifted to drink (poor guy on plane seated I front of me, and my husband when we stopped in the mountains.) Fix: when using when air pressure changes, unscrew top to release pressure, screw back, then raise straw to drink.
