Exactly what you are buying nothing more nothing less
Its exactly what it does!! It flashes every thirty minutes to remind you to drink! I quiet like it because while I work 16 hour days I usually forget to drink. So when I see that flash in the corner of my eye I am good!<br /><br />The only con I have against it is it does fit almost all bottles, however once you stretch it around it around a large bottle good luck getting it on to a normal water bottle. However, because it is not attached to the band, using a simple rubber band works just as well!<br /><br />A little to pricey for what it does, but still good for those like me that never remember to drink water!
