TAL Stainless Steel Modern Tumbler Water Bottle 20 fl oz, Pink Glitter

On the first day that I used the cup, I filed it with ice and water and took it to work. After drinking the water, I added more water to the ice and drank about half of it. When I went home, I realized that I had forgotten the cup in my car. When I got a chance to go out and opened the container to empty and refill it and there was still ice in it and it was still extremely cool. I also put coffee in it before, and it kept my coffee warm for over half of the day without rewarming. I would highly recommend, plus the colors are just to vibrant and pretty.

I can't find anything wrong with this bottle! It does what it says, keeps cold drinks cold for around 18-24 hours and hot drinks hot for about 12 hours. With cold drinks I found if you put cold water with no ice it stays cold for about 18 hours. If you add ice it's 24. When tested in a hot car, ice water was still ice cold after 5 hours! I tested hot tea in the refrigerator, 6 hours later the tea was still hot, but noticeably not as hot as before. There was never any condensation on the outside of the bottle, and it doesn't leak. Easy to clean with a bottle brush, the mouth was wide enough for most ice cubes. Best bottle I've had in years!
