Customer Ratings & Reviews

My wife and I have tried many different travel bottles to find one that holds a reasonable amount, is easy to carry, keeps temperature, and actually fits in our vehicles' cupholders. The Ninja Thirsti is as close to perfect for us as any bottle we have ever tried and looks nice too. Pros - Solid feel, with a nice textured exterior that looks great and is easy to hold. - Integrated rubber carrying handle works great (you can flip it down to carry the bottle with your hand thru it for a better grip or flip it up and carry the bottle with the rubber handle by itself). - Twist open cap remains attached, even when open for a drink, and seals well with no leaks when closed in any bottle position. - Awesome at keeping fizzy drinks fresh. I found that my carbonated beverages stayed fresh for well over 24hrs and still opened with a satisfying hiss. - The 18oz size is a perfect fit for every vehicle cupholder I tried (2017 Mini Countryman, 2021 Toyota Highlander, 2022 Toyota Sienna, and a 2020 Jeep Gladiator). - Stainless interior is easy to clean. Ninja says the bottle is dishwasher safe, but we found it easy enough to clean with just soap and water. Things to Consider - The Thirsti is good at keeping things at temperature, but I was not able to get the 24hrs for cold items and 12hrs for hot items that Ninja claimed. I found the limit for me was about 8hrs, before hot things became just warm and iced drinks (half ice/half liquid) completely melted. - It is about a 1/2" too tall for our older single cup coffee maker, even with the drip tray removed - not a deal breaker, but it just adds an extra step of brewing hot drinks in a shorter cup and then pouring it in to the Thirsti.

The Ninja Thirsti is a game-changer when it comes to travel bottles! It's compact, lightweight, and has a sleek design. The 18oz capacity is perfect for staying hydrated on the go without taking up too much space in your bag and fits nicely in my cup holder. One of the standout features of the Ninja Thirsti is the new Triplethermo technology. This model is designed to keep your drinks colder and fizzier even longer. Cold for 24 hours. Ice for 2 days. Hot for 12 hours. Now my real life test.. I will say I do think it keeps colder longer than my competitive leading brand, but the fizz was hard to tell in the short time have used it so far. When I tested how long the ice would last, I filled it halfway with ice and 12 hours later I had some left. So, you will get a couple more hours than the 12, but not 2 days, unless maybe you fill it packed with ice.. just my opinion. The leak-proof lid is another highlight of this travel bottle. You can toss it in your bag without worrying about any spills or leaks. Plus, the wide mouth makes it easy to fill up and clean. However, it does take two hands to open and close. I do prefer the option of a push button you can open with one hand. I am so used to my current model with this feature, that I find it hard to get used to this twist top. (-1 star) The carry handle is large and made of rubber, which make it very comfortable to carry and hold. I also appreciate the durable construction of the Ninja Thirsti. It's made from high-quality stainless steel that can withstand the rigors of travel and everyday use. The bottle is also BPA-free, which is always a plus when it comes to health and safety. Overall, I highly recommend the Ninja Thirsti 18oz Travel Bottle. It's a reliable, stylish, and convenient companion for all your adventures. So whether you're sipping on a refreshing iced water or enjoying a piping hot coffee, this bottle has got you covered! Cheers to staying hydrated wherever you go!

The Ninja Thirsti 18oz. Travel Bottle is nicely designed with a clean, modern look and a flexible silicone handle. The round screw on top and square drinking cap both seem to seal tightly. The bottle feels solidly built and fits nicely in cup holders. The part I was excited about was that I could keep soda cold and fizzy for 24 hours. This bottle is unique since most travel bottles cannot hold carbonated beverages or it could build up too much pressure and ruin the seals and/or could be dangerous. I tested the bottle with soda and no ice since I do not like my soda diluted by melted ice. The soda stayed cold and fizzy all day but the next day it was not cold enough but it was still pretty fizzy. I felt like the cold for 24 hours claim did not work well. I think the 2 days ice claim works fine. The LeakLock lid worked well in that it did not leak or spill at all. The bottle is also BPA free and is made of 18/8 stainless steel. Overall this is a really good start at a BubbleLock travel bottle but I don’t think it works as we as it should.
