Durable and really does increase your water consumption!
This thing is awesome and I have purchased 2 more for friends! It really helps me drink more water. It goes off every so often when you don't drink, and sometimes I worry I miss it so I drink more just to be sure haha!<br /><br />Sometimes it doesn't register that I drank and continues blinking. I think it might be when it is on the side of my bottle, vs the front or back, but need to test further.<br /><br />My friends got left in the street over night when it rained and it still works great!<br /><br />I love that it goes to sleep when theres no light, as soon as I get up in the morning it wakes up when I move around!
