LOVE THIS BOTTLE. Seriously. My friend ordered the gallon size and sang its praises. I don't need a gallon so I got this one and man, there's a reason this girl is my friend!! This bottle is the best find. I have tried like every other kind of bottle and this one is my favorite. It doesn't make the water taste weird, it holds four bottles' worth of water (my daily minimum goal), it's easy to drink from, I love the straw action, the markings are just fun (I'm usually done with the whole bottle long before 9pm), and the carrying strap is fantastic. This bottle doesn't leak as long as the lid is on correctly lol I do have to adjust the straw sometimes and push the white tip onto the straw because if it gets loose, it's not a smooth drink. It drinks like a cracked fast food straw. That is a very small price to pay for such a wonderful water bottle and I never mind having to fix it. Thank you Fidus for bringing this water bottle to the world!!!
