This is so far my Best container for water ,cold drinks. It keeps all my drinks Ice cold . For 2 days . I love it .Ninja products are tge best.

 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.

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 product overall. Travel Bottle is well-built, durable, and keeps drinks secure without leaks. The finish looks sleek and premium, and the size is perfect for daily use. Very satisfied with the quality and performance.

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.

Love it. Keeps water very cold. Easy to use and easy to clean.

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.

I bought this as a gift for my nephew. He said it's the best cup he's ever had. He loves that he can use it as a cup or a thermos, as he can use it for hot drinks as well as cold drinks. You won't regret the purchase.

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

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!

Pairs well with the drink machine. Keeps my drinks cold no problem.

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.

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

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.

It’s very durable and has excellent insulation, so you can keep enjoying hot drinks for a long time.

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

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

Keeps drink cold. Easy to drink out of and keep clean. Lives up yo the Ninja brand of another great product

So I did not get to use it, whichever store location sent this to me it was poorly packed the box was opened at the top it’s like they just threw it into the box scratches on the top and bottom so I can’t say if it does what it was made for returned the very next day. Otherwise it feels and looks sturdy would purchase again but from another supplier’s.
