I love the insulation of keeping my ice water and that it hasn't leaked, so far. There are 3 lids, I've tried 2 so far. The straw lid kept the ice in the ice water for well over 12 hours and still cool at 24 hours and it doesn't leak when the straw is down.The lid you take off to use the bottle doesn't leak, that's great. But the one experience I didn't like was that lid has a clip to hook it on something and I used it on my basket and as soon as I hit a bump, it fell to the ground. Luckily it made enough noise that I retrieved it. I wish the clip was sturdier.But other than that, it's a great bottle for what I use it for.
