Customer Ratings & Reviews

 I am a carbonated beverage person and it just doesn’t stay as carbonated as I would like without it. I make them in little 6 ounce portions multiple times now I can make 24 ounces and put it in here and know that it will stay bubbled. I know the design on this is fabulous. I love the lock that locks in that carbonation. I literally got it today and I made 24 ounces through two ice cubes on top of that and drank all day with it, and it’s still carbonated so I am no longer skeptical.

Nothing really fancy about this tumbler, but it works great for my needs. It's well built; I know because I've dropped it a few times. It has minor scratches, but no dents and it's still going strong. It keeps my water cold and holds ice for up to, I would say about 2 days. I love it.

This bottle is great! I make at least 2 bottles of carbonated water a day and this is a game changer! Keeps it cold and bubbly and doesn’t leak!

We’re a big soda stream family, so this is perfect. Now I can sip on my fizzy water throughout the day and it will still be cold and carbonated. Little pricey though.

This is a great investment, I purchased it as a gift for my wife and she loves it. I t keeps her soda water cold with less ice for the day unless she drinks too much water. It is well built, rugged and easy to carry!

This is the best water bottle i have. It keeps my water cold for more than 24 hours. I recommended 100%

The Thirsti travel bottle is actually a good product. Cold water stayed cold for 2 days then stared to get warm. Soda carbonation stared to loose fizz after a day. Ice stayed frozen for a 36 hours (no fluid added). I cannot comment on anything warm. The drink cap on lid keeps fluid from spilling, but because you will need to twist it not ideal for cycling.

Great size, keeps contacts cold, and no leaking! Great value!

I have bought 5 for work and it is very well made. With most after months of using it can become tarnished or spotted these have nit done that. Mostly use for tea and at times coffee.

Great water bottle! Keeps my drinks really cool! I like it for travel!!

Keeps water cold for a very long time and fits in standard cup holder in car.

It’s ok. Soda probably lasts a little longer than just sitting in its original plastic container. After few hours, you will start noticing degradation in bubbliness. Which could probably because you often open it whenever you drink. All in all I would still buy it again.

I have bought a lot of water flasks. Often, they begin to leak, or they are hard to clean or I drop them, and they break. So far, I've experienced none of these problems, and it is by far my favorite flask.
