The core tritan autospout 24oz blue corn water bottle is the best water bottle i have tried. Its comes in nice size. And i love that its very easy to hold the water bottle with the handle on top of bottle. The cover come off nice and easy to fill it. And when you want to use it. All you do is press the button on the side. And it pops up the spout to drink from. When you are all done you just push the spout back down to shut. It stay very clean from having the open and shut spout. And most of all i love that the spout is rubber so when you are drinking its soft on your lips. I am very pleased with this water bottle. And all it has to offer. It's so great for a person who loves to drink water like myself.
