I've been using this Ninja water bottle for a couple weeks and I have found it has worked really great at keeping my iced water. I like the twist top cap you use to drink from, though I am concerned it might break later on down the road because of how floppy it is. The swing handle used to carry the bottle is comfortable to wear while using it. I also like that it holds a good amount of fluids but still small enough to fit in my cup holders in my car. I recommend this.
