I've enjoyed using this water bottle for the last couple weeks. I will admit that I did think that the water would be kept colder after a couple house. I actually expected ice cubes to remain somewhat whole within 2 hours of adding it to cold water and taking the bottle on the road, but that was not the case. Maybe I had unrealistic expectations!

I do like the thinner base that allows the bottle to sit nicely in my car's cupholder. The bottle I was using before had a bigger base and always fell and rolled around my car making it difficult to access when I needed a drink!

The one ting that is weird is that when the bottle is almost empty, when using the straw, the bottle gives off a somewhat annoying whistle, which as you can imagine, is even more annoying in the middle of the night when I am trying to stay quiet!  It's annoying, but not a deal breaker!
