Ninja - Thirsti 18oz. Travel Bottle - Seafoam Blue

After several days of using the Ninja Thirsti 18oz Travel Bottle, I am amazed by its exceptional performance in holding cold and hot drinks. Its design embodies an elegant minimalism and features a thoughtfully crafted handgrip with flat areas on both sides, making it effortlessly easy to hold. This bottle has a lightweight construction that instills a strong sense of durability. Its dimensions are perfectly calibrated, allowing it to snugly fit into car cupholders and the pockets of my backpack. What's truly remarkable is its consistently effective leak-proof design, which has pleasantly surprised me by reliably preventing spills, even during the rigors of my daily backpack use. Beyond its standard features, I appreciate how the bottle's lid remains securely in place when open, thanks to a clever hinge-notch mechanism. The standout feature is its exceptional ability to maintain the temperature of both hot and cold beverages flawlessly. Crafted from stainless steel, it not only signifies durability but also resists rust. The double-walled vacuum insulation is a game-changer, ensuring that drinks remain refreshingly cold for up to 24 hours or hot for 12 hours. Furthermore, the addition of a leak-proof lid and a convenient silicone handle enhances its overall appeal. In conclusion, I wholeheartedly recommend the Ninja Thirsti 18oz Travel Bottle to anyone in search of a travel companion that possesses not only sturdiness and leak resistance but also the remarkable capability to preserve the ideal temperature of beverages for an extended period. Furthermore, it offers the convenience of easy cleaning in the dishwasher while also being free from BPA.

Every morning I make my wife a soda water with our SodaStream and put it in this bottle before she goes to work. It worked great for a month, but yesterday it exploded while she was driving to work and almost made her crash the car. The whole top of the bottle came flying off. Really wouldn't buy this product its a safety hazard.

The Ninja Thirsti Bottle is an excellent addition to any travel set or road warrior kit. I haven't found a cup holder it didn't fit into, and it's been easy to fit into life. The sleek Thirsti bottle holds 18oz of liquid, whether hot, cold, iced, flat or FIZZY! There are other sizes, but this is the right amount for me. The bottle is 100% dishwasher safe, BPA-free, and has an 18/8 stainless steel body brilliantly polished interior. The mirror-like finish is the secret to the fizz protection, and it actually works! Now, back to the outside of the stainless-steel bottle enveloped in a grippy matte finish—the middle is a crimped flat impression on two sides for added grip and comfort. The silicone strap is nice to carry and easy on the hands. The lid is almost 100% plastic with proper silicone seals and hardware for a nice squared, easy-to-twist lid with a leak lock to protect even carbonated drinks from leaking and making messes. The bottle emanates premium vibes and is part of the Ninja Thirsti System. You can use this with beer, soda, juice, or anything carbonated you love or create. The bottle DOES actually make a difference in preserving the carbonation - all based on simple science. Porous vs sealed, like waterproofing, BubbleLock seals CO2 in so it doesn't go out. I am not a soda drinker, so the closest I could get was beer and a popular green bottle of "Natural Sparkling Mineral Water." The popular green plastic bottle of carbonated mineral water went flat about 2 hours before the Thirsti - Another win! In my photo, you can see how a regular bottle (left) just lets the bubbles burst and there is nothing in the water. The Thirsti bottle (right) doesn't allow anything to stick and actually repels CO2 from sticking and dispersing making it last longer. Keep the lid on and you will REALLY notice the power of CO2 preservation! I tested for heat, cold, and ice in my simple testing. I filled the bottle with hot coffee, iced water, refrigerated carbonated water, and BEER for a babysitting beer-drinking guest. THIS PASSED WITH FLYING COLORS! All claims were confirmed. Ice survived over 48 hours in the bottle. 72 hours - the 3rd day of testing, my ice water was STILL cold to confirm the 24-hour cold claim. Did the coffee test for the hot test and made coffee at 6 am that remained hot enough to sip right before 6 pm for results. The babysitting beer guest watched a complete day of football from 1 pm to 10 pm, and the beer still had bubbles, and it was still cold! WHAT!? My quality concerns are limited to the bottle lid and the interior finish. The weakness of many water bottles is the lid and handle. Like others, all plastic and connected by a flexible flap. After one or two drops, I don't think this will make it if you land on the lid, honestly. The comfortable silicone handle may fit 3 to 4 fingers to hold the well-built stainless-steel interior, insulated layer, and rugged exterior. I like the square cap instead of a traditional circle; it is easier to grip to tighten. I don't know how like the coating will last as you are discouraged from rubbing it as it could dull. This bottle works precisely the way it says, and all claims are valid in my testing. It keeps your drinks nice and cold, and if there is carbonation, it definitely makes it last longer than if you put it inside a regular bottle. There were no leaks or accidents from carbonation so if you want something specifically for carbonated beverage preservation over longer periods, this is worth a try. I haven't seen any other bottles specifically marketed for carbonated beverages. Maybe this could be a new trend.

Wow! This works! The Ninja Thirsti 18 oz is a travel mug / bottle from Ninja. I have owned Ninja appliances for years, and when I found out they were putting a spin on the travel mug / bottle, I knew I had to try it. This is my new go-to mug for travel or just around the house. This bottle works great. Experience: I decided I would put the Ninja Thirsti up against insulated tumblers and an opened bottle of soda. After a day of waiting, the Thirsti was still cold and fizzy whereas the opened soda bottle and the insulated tumbler had long since gone warm and flat. I like the twist close lid. I never had any leaks. Everything is constantly perfectly sealed. Cleanup: Ninja advertises the Thirsti as dishwasher safe, but to prolong the life of the bottle, the instructions recommended hand washing the bottle. However you decide to wash the bottle, you should know there are three different rubber fittings inside the lid. Should you ever lose or need to replace those rubber gaskets, Ninja does sells replacements for the three gaskets on their website for two dollars apiece. Conclusion: I really like this travel mug. I prefer to wash it by hand, but washing in the dishwasher works as well. Ninja already makes many of my go-to appliances, this is now my go-to bottle. If you find yourself seeking an insulated bottle to keep your drinks cold, warm, and / or fizzy, you should check out the Ninja Thirsti. 5/5

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!

This Ninja “Thirsti” is a well made travel bottle. Full 24 once holds enough for the whole day. Made from 18/8 stainless steel, the construction and fit and finish are impeccable. Designed with an ultra smooth “BubbleLock” interior finish, that helps keep carbonation bubbles from forming. Couple that with the “LeakLock” spill proof lid, and the “fizz” stays in the drinks far longer. When opening the lid, it has a friction lock to hold it open when drinking. The “TripleThermo™️” can keep cold drinks cold for 24 hours, ice for 2 days, and hot drinks hot for 12 hours. This will fit most cup holders – larger than 3.15 inch, and has a convenient silicone carrying handle. I really like the feel of the silicone handle - not hard plastic. The stainless steel resists scratches and dents, and is safe for the dishwasher. Overall, this is a well built travel bottle, and does an excellent job of keeping drinks hot or cold for quite a long time. Perfect to take biking, hiking, to the gym, pool, or any sport or outing. Highly recommended.

Verdict: The Ninja Thirsti 18oz. Travel Bottle is a stylish bottle that keeps cold drinks cold, hot drinks hot, and fizzy drinks fizzy! It works, and it works for longer than my old coffee mug, and definitely better than my current plastic water bottle. As a sparkling water lover, my favorite feature is the bottle’s ability to keep my sparkling water cold and fizzy for most of the day, even when on the go. First impressions. This bottle is fairly tall, mostly because of the extra footprint of the twist cap. I really like the silicone handle because it swivels, it’s comfortable to hold, and if you grab the bottle on the top end, the handle just folds under your hand so it’s still easy to grab. It fits in all my car cup holders. The square twist cap is easy to grab and turn. This bottle looks very nice: sleek and stylish. Performance. This bottle works well in all applications: hot, cold, ice, and fizzy. While I appreciate the versatility of the bottle, I mostly care about keeping my coffee hot and now keeping my sparking water cold and fizzy. On my first day of using this bottle, I noticed that my coffee was indeed hotter a few hours after making it then it has been for the last few years of using a different mug. On my second day of using this bottle, I decided to try it with my daily sparkling water. Normally, I take a cold sealed 1L sparkling water plastic bottle and toss it in my backpack for the day before leaving for work. By noon, my sparkling water is still fizzy but warm. With this bottle, my sparkling water stays cold all day. The only downside is that I can’t fit the entire 1L sparkling water in the Ninja bottle, so now I pour most of my sparkling water in the Ninja bottle, and I start drinking what is left in the plastic bottle first while it is still cold. Then, when I switch to the Ninja bottle about mid-day, my water is still cold and fizzy. Now I only use this bottle for fizzy water, but I am considering buying another one for my coffee! Technology. The technology in this bottle is impressive. LeakLock prevents any leaking from the cap, even with fizzy drinks. Triplethermo shielding keeps drinks cold for 24 hours, ice for 2 days, and hot for 12 hours. Finally, the interior is “super-polished” to prevent nucleation points that cause bubbles to pop. This feature, along with the BubbleLock lid keeps drinks fizzy for longer. When opening the cap, you can hear a very satisfying “woosh” from the pressure released inside the bottle. This bottle is so good that I wish I could store my entire 1L sparkling water in it, but that would probably make the bottle too big and unwieldy. Things I love. - Stylish bottle - Easy to use square twist cap - Keeps my sparkling water cold and fizzy all day! - Stainless steel with durable protective coating - Comfortable silicone handle - Dishwasher safe! - Triplethermo: cold for 24 hours, ice for 2 days, and hot for 12 hours!! - Five-year warranty! Things I don’t love. - Nothing… it’s amazing! Overall, the Ninja travel bottle is a win! It hits the mark on all advertised features, and it checks all the things I care about. Most importantly for me, it has improved my daily consumption experience of sparkling water. Lastly, I think the value for the money for this bottle is excellent, specially compared to the prices of many other bottles in this space. I highly recommend this bottle.

My new go to bottle. I spend a lot of time in and out of an office that requires all drinks to be in sealed spill-proof containers and this Ninja Thirsti travel bottle fits the bill. In fact, the more I use it the more I appreciate how well designed it is. Not just aesthetically, but there’s a lot of seemingly minor details that make a big impact on how convenient this travel bottle is to use. For instance, there’s a silicone leash that’s integrated into the top half of the body, no biggie, but the flat hinge for the leash makes a perfect anchor point to help twist the top half off without your hands slipping. Same with the 2 flat edges that run along the bottom main body which helps you maintain a good grip on the bottle without it twisting in your hands. Even the bottle cap itself is well thought out and possibly the best part about it. The square shape of the cap makes it easy to open, even one handed, and the cap leash has a detent that prevents it from hitting you in the face when you drink. Inside, the body has a smooth mirror polish which supposedly helps carbonated drinks stay fizzy longer. I can say that it definitely works, however I don’t know if it’s actually any better than any other sealed bottle. On that note, the sealing on this travel bottle is fantastic and has been 100% leak free in the week I’ve had it. It also does a great job of keeping drinks hot or cold. I wouldn’t say it’s the best I’ve had in that regard, but it isn’t a slouch either. I pack it with ice and water in the morning and the ice survives multiple refills of water and Sprite throughout the day until the evening. In terms of hot liquids, I’ll put hot tea in it at night and it’ll still be warm the next morning. Not hot, but warm enough to not need to heat it back up. The body also seems to stay at a neutral temperature which makes it easy to constantly hold. It doesn’t even feel warm when I put hot tea in it which is great, but a little jarring when you take a sip and forget that you put something hot in it. I can’t comment on the durability because I haven’t dropped it yet, but it’s made with stainless steel and BPA free plastic. It’s also dishwasher safe, though the instructions recommend hand washing if possible. Overall, this is an outstanding travel drink bottle and I highly recommend it. It has a leak proof sealing system, is easy to open, the cap doesn’t hit your face, keeps drinks hot and cold for over 12 hours, fits in cup holders, and looks pretty spiffy. As a designer, I also love the functional attention to detail like the easy open cap and flat grips. This might be my new go to for Christmas presents this year. Great job Ninja! PROS - Thoughtfully designed - Square cap easy to twist open - Built-in silicone leash useful - Leash hinge good anchor point to twist off top half - Bottle cap hinge prevents it from hitting your face - Flat edges on sides for easier grip - Fits in regular cup holders - Keeps drinks fizzy - Leak proof - Maintains hot and cold temps for hours - Attractive design - Machine washable - 18oz size CONS - Sometimes cap doesn’t twist on properly - Don’t know if it really keeps drinks fizzy longer than other sealed bottles
