Review: Keeps drink cold for over 24 hours - My 10 year old daughter picked this one out due to how pretty it looked and loved the strap. It keeps ice for almost 24 hours. Love the 3 different caps that come with it.
Review: Quality Bottle - So I've had this bottle for a week or so and I'm relly enjoying it. I live in a hot sub tropical climate and wanted a drink bottle that stays cold and this one really does. I bought a big ice cub mould and those big cubes have lasted for around 5 hours in the bottle. Even after they have melted the water is fridge temperature cold for around 20 hours and then it's still very refreshing until around 24 hours. I'm really impressed. I also love the colour and the surface finish of the bottle is really nice and very anti slip. I find the straw really convenient and I love that it closes tight so no bugs can go in there. One thing I would say is with the straw lid, its not water tight. I haven't tested the other lid. I just carry the bottle around my house so it doesn't bother me. I do like the strap that comes with the bottle but it's a bit tricky to attach and I worry that the plastic ring might eventually break further down the line, but not anytime in the near future I don't think. All in all I would 100% purchase this bottle again and may get another for my husband.

### ⭐⭐⭐⭐⭐ Great water bottle with handy strap
*by S***N on July 5, 2026*

Great water bottle. Keeps drinks cold for hours, even when I'm outside in hot weather. I like the handy strap so it's easier to carry. The only downside is that it does not fit in a car cup holder. It's more of a bottle you'd take when you're going to be outside for a longer period.
