Ninja Thirsti 18oz Travel Water Bottle

This insulated 24oz bottle works great! It keeps my 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.

Hold carbonation for at least 24 hours. Keeps drink cold just as long.

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

This was provided as a freebie when I bought my Ninja Thirsti recently. I was skeptical about the claim that it would keep the fizz in my seltzer for an extended period of time. Lo and behold, it kept the carbonation in my drink all day. It kept cold as well. The only thing I would like is a flip top closure instead of needing to unscrew the top every time you want a sip. Otherwise, it's great. Thinking of purchasing the 24 oz.

I had high hopes for this bottle, but I've had it for several months now and am disappointed with the product for two reasons: 1. It does leak. I use this bottle solely for carbonated water and keep it in a lunch bag on my drive to work. If the bottle gets jostled around in the car, my entire bag is soaked. Even with the bottle placed upright in a cup holder, if the water is super fizzy, there will be water leaking from where the bottle screws together (not from the cap). I have tried using superhuman strength to tighten it, but that doesn't seem to solve the problem. 2. I have washed the bottle cap both in the dishwasher and by hand and there is a mildew smell coming from the screw cap that I cannot get rid of. I have tried removing the gasket and using a tiny scrub brush to get into all the nooks and crannies but it still lingers. Due to these issues, I've been pretty disappointed, and I've basically stopped using this bottle. It does a decent job of keeping the water carbonated, but I would not say it's all that stellar at this. I used to use a different bottle that kept water super carbonated, but it was not designed for carbonated beverages and warned against doing so, hence why I purchased this bottle.

Love this.my drink stays cold all day and carbonated all day.

I really enjoy my new travel bottle. Neat that I can stick it in the dishwasher too.

Top tier bottle. It keeps my water cool for traveling in this humid weather.

Love my new Ninja Thirsti travel bottle. Just been on a trip and it stayed cold for two days. Easy to drink out of and to clean.. will be using it lots.

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.

love how it looks and keeps the carbination inside the thermos.

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.

This travel bottle was a free gift when I purchased my Ninja Thirsti machine. I didn't think I would need this bottle, but it was free, so that was a plus. One evening I wanted a drink from my Thirsti (I don't remember the flavor) but decided on a whim to use the travel bottle. As I watched TV, I dozed off and woke up hours later. There sat my travel bottle and I cracked open the cap and heard that psssst sound letting me know my drink was still carbonated. I took a drink and not only was it still carbonated, it was still cold! I was impressed. Now when I am making a drink with my Ninja Thirst, I am also using my travel bottle. Life is so much better when the drinks stay cold and carbonated.

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

This is just what I wanted. Really like the opening/spout.

Love this bottle very well made, and keeps my water cold. I was really surprised to see it keeps my water carbonated with the Thirsty maker. Great Product and the warranty amazing!

Bought this and happy I did, keep my drinks cold and keeps the bubbles
