Ninja Thirsti Water Bottle and Flask 530 ML With Leak-Proof Lid, Designed For Carbonated, Hot & Cold Drinks. Ideal For Travel & Sports, Triple Insulated, Stainless Steel Bottle, Grey, DW1801EUUKGY

The Ninja Thirsti Water Bottle and Flask 700 ML is a great everyday bottle – durable, stylish, and very practical. It keeps drinks cold for hours, has a leak-proof lid, and feels high quality. Perfect for the gym, work, or travel.

I've been using this bottle daily for work and when out walking, and my first impression is that it feels noticeably more substantial than most reusable bottles. The stainless steel construction gives it a premium feel without being excessively heavy when empty. The insulation performs well. Cold drinks stayed chilled for most of the day, even after being left in a warm car for a while. I also tested it with hot coffee and it remained pleasantly warm several hours later without the outside of the bottle becoming hot to touch. One feature I particularly liked is the leak-proof lid. I've carried it in a backpack alongside a laptop and paperwork without any leaks or drips. The lid screws on securely and feels well made. The bottle is also designed for carbonated drinks, which isn't something every insulated bottle handles well. I used it with sparkling water and had no issues with leaks or pressure build-up when opening. The 700ml capacity is a good middle ground. It holds enough to avoid constant refilling but isn't so large that it becomes awkward to carry around. The opening is wide enough for adding ice cubes and makes cleaning easier. The only minor downside is that the bottle is quite chunky compared to slimmer sports bottles, so it may not fit every car cup holder. When full, it also has a bit more weight than plastic alternatives, although that's the trade-off for the insulation and build quality. Overall, it's a well-made bottle that feels durable, keeps drinks at the desired temperature for hours, and is practical for everyday use, commuting, travel, and exercise.

I’m really impressed with the Ninja Thirsti bottle – it’s stylish, well made and feels very durable. It keeps drinks cold for hours, and it’s great that it works just as well for sparkling drinks as it does for water or hot drinks. The insulation is excellent, and my drinks stay cold all day. The lid feels secure and genuinely leak-proof, so I’m happy to carry it in my bag without worrying about spills. It’s also comfortable to drink from and easy to clean, which makes it great for everyday use. The only thing to be aware of is that it’s a little heavier and bulkier than a standard water bottle because of the insulation, but that’s expected for the performance you get. Overall, a high-quality bottle that looks great, keeps drinks at the right temperature, and is perfect for daily use at work, the gym or on the go.

Great bottle, can even keep things fizzy. Keeps drinks cold for ages. Easy to clean amd use. No straw which is great

Very pleased with my ninja heatstore! I like the feel and the look of this flask. I bought the 300ml. I am quite particular with mugs I choose, they have to be a certain shape, weight, the ceramic needs to be the right thickness and the handle has to be right size to fit my fingers comfortably and not too flimsy so that it properly holds the weight of the mug. I know this sounds crazy. The goldilocks of mugs! 2. I never liked thermoflasks because they always left a taste and awkward to drink from which I can't say that about the ninja heatstore. 3. I like spout. There is no dribbling as you get with a flat lid with just a hole to drink from. 4. No condensation 5. No leaks whatsoever! 6. Reaches a drinkable temperature quickly. No Russian roulette game of burning the tip of your tongue. 7. Open and close with one press. One hand needed only. 8. Feels durable The following reasons are why I haven't given it 5 stars. 1. The base is a wider diameter so it doesn't fit the cup holder of my 2020 suzuki swift (although luckily it fits in the drivers door compartment). As its leak proof, I am happy to throw it on the passenger seat. 2. To open the lid to give it a good clean is simple although may be difficult to undo for anybody with dexterity problems. It may get easier with time or practise. You lift the lever underneath, turn the dial which may be stiff for some and the button pops off for cleaning. Remember to close the hidden dial, the button will not secure otherwise. 3. It may feel bulky/ heavy for some. Depends on individual preferences. 4. The spout could have a wider opening so closer to mug drinking experience- Personal preference. 5. Could keep drinks hotter for longer. Breakfast tea/ coffee is lukewarm after 6 hours. Although a lemon and ginger tea was slightly warm in the morning left over night. The technology to quickly make your hot drinks a drinkable temperature could be why it's not hotter for longer. 6. Not a fan of the heat technology logo. It looks like a prototype- Personal preference. 7. More colour options. I can't comment on dishwasher cleaning as I don't have one.

Great bottle. I honestly was sceptical at its capability to keep things fizzy but to my surprise it works amazingly plus has kept my drinks cold even in the warmer weather. No need to worry about any leakage either as I even shook the bottle and it was completely fine. The size of the bottle could be quite big and cant really fir in some of my smaller bags but I needed a larger size bottle plus it fits in 2 cans of fizzy drink perfectly.

A Ninja Thirsti water bottle works well for everyday use and is easy to take out and about. It feels solid without being too heavy, and the size is practical for carrying in a bag. Drinks stay cold for a good amount of time, which makes it useful throughout the day. The lid is secure and doesn’t leak, so it can be used without worrying about spills. Overall, a simple and reliable bottle that’s easy to use on a daily basis.

Love ❤️ love ❤️ love ❤️ My ninja bottle, I waited a long time for someone to invent a bottle that allows carbonated drinks in it. Good make, good price,lush colour and keeps my fizzy drinks chilled and fizzy. Totally recommend this product

très bonne bouteille isolante ,bon design , bon choix de couleur

Maintient très longtemps, l’eau froide et l’eau chaude de très bonne qualité. La hanche permet de le porter en promenade autour d’une ceinture de pantalon. Je recommande.

Looks like it's going to date as it says. Kept fizzy water well for over 22 hours.

It’s worth the price the quality are so much good. I love it.😍

I was happy with this. Good build quality. But then a few weeks in, it turns out they saved on the cap by making it plastic with metallic paint, and the paint has almost fully come off now, even tho this item is advertised as being dish washer safe.
