When I saw this bottle, I said, yes, I need this for my boys who play soccer. Um, how do we use it? We use it for soccer practices, soccer games. My boys fill it up with ice and water, take it to the games on the go. Perfect. Fits right in their side pockets of their backpacks. What do I love the most? That is very convenient, easy to wash, easy to clean. Um, anything that didn't work for me, um, I don't think so. I was just, um, sucked that I didn't find it earlier, but now that I have, we have it, we have 4 bottles actually. Um, always on the go, easy to wash, easy to clean. Let's go.
