Ninja Thirsti 18oz Travel Water Bottle

This insulated 24oz bottle works great! It keeps my drinks cold and fizzy .

I bought this bottle a couple of weeks ago and I love it. My carbonated drinks don’t lose their fizz and they stay cold.

Works great love the quality and how it keeps drinks cold and fizzy

This works exactly as advertised. My drinks stay cold and I don't lose carbonation, all day. It does need to stay upright, because it leaks if you drop it on its side, or at least the one I have suffers from that issue. I haven't taken the time to check the gasket, so it might just need to be seated in the lid better. Overall, it's an amazing product.

I am desparate, so I am keeping this, but it is pretty awful. I've only had it a few hours, so I cannot confirm that it actually keeps the fizz, but I can say that it is impossible to drink from without spilling water all over yourself. What it needs is a straw/mouthpiece opening so that you don't have to open the water bottle all the way in order to drink. I am not optimistic that the fizz won't go within five minutes. So, I may yet have to return this item. Very, very disappointing.

Finally, a bottle design specifically to use with carbonated beverages. It works! And the small version, 18 oz size, is easy to hold. Definitely recommend tothers.

I love the bottle it doesn’t leak at all. It’s perfect

Best bottle I've ever had, I drink sparkling water because I hate still water and this bottle keeps the carbonation and cold all day. The handle is perfect when I am carrying grocery bags unlike the others with side handles and your drink spills out. Ninja does it again.... thank you.

I am finally glad Ninja has the drinking bottles. I have everything Ninja. If Ninja makes cups like the Stanley and everyone else, I would buy everyone of them.

I'm so happy that I bought it I would buy it again

We have had this for about a year now. WE LOVE IT!... We are empty nesters so we don't need a whole pot of coffee every day. My husband prefers the pods but I prefer the fresh grounds so it a win win either way!

[This review was collected as part of a promotion.] Heavy duty. Doesn’t leak, keeps product hot and cold and seems to hold up to scratches/dents. There are a lot of beverage containers on the market and it’s hard to differentiate. If the price is right, this one is worth a shot

I bought this and was so excited to use it! Only to be disappointed, the actual mouthpiece is a bit small, and cover is difficult to keep open while drinking, the way it sits there's liquid around the mouthpiece so you feel like your dribbling. I thought i purchased a lid with a larger mouthpiece but received the exact same thing. The positives are it fits the Thirsti drink system, keeps your drink cold, carbonated, and the lock system is great.

[This review was collected as part of a promotion.] I got this bottle a few months back and love it. Like any Ninja product, it is made from strong durable materials. It has a twist-off cap and a rubber handle for easy use. As a sparkling water lover, this bottle is great and doesn't make your carbonated drinks go flat.

[This review was collected as part of a promotion.] I've had this Ninja Thirsti travel bottle for about a month now and am using it almost daily. I've had hot liquids in it, like hot chocolate, but have mostly used it for water or diet soda that I drink. I usually go for lunch to places with soda fountains, and I get my refill of soda put in the Thirsti, and it keeps it cold for hours. And I've had soda in it overnight and it always keeps in the carbonation to keep it ready to drink. I also use it for water for my workouts and have left it out in the sun for hours and the water still stays cold. I like it's skinny enough to fit in the side pocket of my backpack, so I've taken it on trips as well. And I really like there are two flat side to the bottle which seem to make gripping it easier. So overall a great insulated bottle that will keep your drinks hot or cold and your soda fizzy! Would definitely recommend. Ninja comes through again!

[This review was collected as part of a promotion.] I'm not into all the reusable water bottles (or trends - unfortunately because I need to drink more water!) ... but I found myself grabbing my Thirsti bottle more and more as I left my house. A big selling (and comfort) point for me is the spout - its smaller like a typical bottle and I love that it isnt one of those big clear disc lids (that always look so dirty). ALSO - and this is huge for me - you can unscrew the entire top to make washing and filling easier. So many of my cups/bottles with smaller spouts don't have this option which means I never use them since they are hard to clean. NOT a problem with Ninja Thirsti bottle. Finally...I had to buy a second bottle because my spouse stole my original one! All around, a great bottle and I'm really happy with it.

[This review was collected as part of a promotion.] I am always on the go and one thing I hate more then anything is when my bottle of soda is flat or hot before I even take a few drinks. I have started using this Ninja Thirsi bottle now and wish I had it long ago. I never dreamed a bottle could keep your drink first sip fresh and carbonated but it magically does just that as well as cold for hours. Great for anyone on the go in my opinion.

[This review was collected as part of a promotion.] This is designed for carbonated drinks. It is really useful for taking cold soda on a trip without needing a whole chiller with ice and the bottles. It is big enough to put a good amount of soda that I can distribute in plastic cups and it is super cold and still very fizzy. It does it's job perfectly.

[This review was collected as part of a promotion.] I love carbonated drinks so this was really perfect for me. I love that my drink stayed cold and fizzy. The bottle is also really durable and secure with no leaks. I would definitely recommend this product.

[This review was collected as part of a promotion.] I am so glad that I decided to give this a shot. I have a lot of water bottles that claim to do all kinds of things- but this one actually works like it says it does. It keeps cold drinks cold for longer, and hot drinks warm for longer. Its really easy to clean and its not too heavy or big. My kids love it for school, they can bring a cold drink and it will stay cold all day. I would absolutely recommend picking one up! Great for long trips. You wont be disappointed with this travel bottle. Great brand, amazing product! Check it out.
