Ninja Thirsti 24oz Travel Bottle for Sparkling Drinks, Fizzier Longer, Leak Proof, 24 Hours Cold, Dishwasher Safe, Insulated Tumbler, Grey, DW2401CGY

Works great and keep my thirsty water cold for almost 8h without ice

Great bottle perfect for the thirsti machine. They hold the carbonation and keep the beverage cold for a very long time. Just as advertised.

I love the size and quality of the water bottle however I think the white should of been whiter it’s more like a creamy white but still love it.

Ninja has done it again! Weeeellll. It has not disappointed. This keeps liquid cold for quite some time. I haven’t tried hot liquids yet. It does keep pop, fizzy for quite a while too. I wouldn’t say it’s revolutionary as other products would likely do the same BUT I think they have something special when it comes to the carbonated drinks. Keeping the carbonation longer is unique among similar products and that’s why I gave it 5 stars. Solidly built and premium material.

I've had two of these (lost the first one in an airport) for about a year and a half. They do a good job keeping cold liquids cool and carbonated. I haven't timed them, but if I add cold water to it, it will still be cold 6 hours later.
