Customer Ratings & Reviews

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 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.

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.
