I have had a hard time drinking enough water for years. I hoped that getting something with a time / checkpoint maker on it would help me and I have to say that it dramatically has. I drink more water now than ever and I'm so happy with my purchase. The football drink bottle says DEHP and BPA free so that's good, I would definitely avoiding leaving it in a hot car as with any plastic bottle you are going to be drinking from, they let you know that right on the instructions so props to them. Very happy customer.
I love this thing so far. I've had it for about a week and it has helped my daily water intake for sure. I've gotten compliments on it and even motivated a couple of coworkers to purchase one as well. My only sons are the color is starting to fade In chunks (a coworker received hers with a big chunk of color missing at the top) and it's kind of hard to get the very last drip, but I'd rather have that problem than drinking through a straw with it.
