Ninja DW2401GY Thirsti 24oz Travel Water Bottle, For Carbonated Sparkling Drinks, Colder and Fizzier Longer, Leak Proof, 24 Hrs Cold, Dishwasher Safe, Stainless Steel Insulated Tumbler, Charcoal Gray

I've tried more tumblers than I care to admit, but the Ninja Thirsti feels like the one that got everything right. From the first use, it’s clear this is built to last. The powder coating feels premium, has a great grip, and hasn’t chipped even after a couple of clumsy drops. The lid is the real winner here—completely leakproof and easy to switch between straw or sip. I’ve tossed it in my bag sideways and not a single leak. Drinks stay exactly how I want them: water icy for an entire workday (yes, ice cubes still clinking at night), coffee piping hot through my commute, and not a drop of condensation on the outside. No more sweaty rings on my desk. The size is perfect—large enough that I’m not constantly refilling, yet it still fits in a standard cupholder. And cleaning couldn’t be easier. The wide mouth makes hand washing simple, but it also goes straight in the dishwasher without warping or messing with the lid. That’s a huge plus compared to other tumblers I’ve owned. Every little detail feels well thought out. It doesn’t just look nice; it works flawlessly. The Ninja Thirsti has already replaced every other tumbler I own, and I can honestly say it’s the one I’ll keep reaching for every single day.

Keeps water cold as ice for a very long time, and also holds the carbonation so we'll from my carbonated water. Proof you get what you pay for. Highly recommend for people trying to drink cold water, or especially carbonated water all day.

Fair warning up front, I have not had this long. It's worked quite well since I got it. I recently started carbonating my own beverages, and this has done quite a nice job of keeping them at least sparkling over an 8 hour shift. It does an excellent job keeping the drink cold (I have not tested anything hot). There's a little rattling noise now, like a bit of solder bouncing around in the vacuumed area of the bottle, but I haven't noticed any decrease in utility. It certainly keeps ice well, I have had it keep ice machine ice in there for a day. It's a bit short of a liter in volume, but it holds a good amount and I've not seen any leaks. The cap takes a bit of getting used to, but as long as you push it far enough towards the handle it will stay put as you drink. It doesn't keep things fully carbonated, but that's no surprise if there's no pressure to keep the gas in the liquid after you drink >half the bottle.

I have two of these and they are wonderful. Fizzy drinks stay fizzy, even 24 hours later. Drinks stay cold or hot depending on which option you chose. I normally like cold drinks and ice will definitely last well over 24 hours.

Ninja products always have great quality. This is a great looking thermos. The water never leaks. There’s no weird taste keeps water cold all day long.

It keeps my water cool and refreshing for a long long time Doesn’t cause funny taste I love that it doesn't have a straw The only issue is that both sizes won’t fit in the cupholder as advertised

Soda was still fizzy even after 13 hours later. Really good bottle for coffee, soda, and water.

Update! I lost the first one of these that I purchased and ordered a new one within 24 hours! Absolutely LOVE this drink bottle!! If you like carbonated drinks, this is a revolution!! First review: I enjoy carbonated drinks of all kinds and everything other drink container I have ever had either let the drinks go flat or spewed when they were opened. This Ninja drink container has solved those problems brilliantly! The secret is that the drinking spout has a screw on lid (not just the container lid but the drinking spout itself). This design does two things. First, there is no carbonation leaking out around a poorly sealed snap on cap. Second, when you begin to unscrew the drinking spout, it gives a little burp of gas that prevents the drink from spewing out when opened (exactly like it does on a screw top soda bottle). So, no carbonation loss and no spewing, but does it keep your drink cold? YES, it will keep ice frozen for 24 hours and keep soda carbonated for at least 6 hours, maybe eight. I've poured a carbonated drink into it at night, gone to bed, and it is still carbonated in the morning. Finally, it is super durable. I've had it for 6 months, used it daily, and dropped it on more than one occasion. It looks and performs as it did when it was brand new. I would give it 10 stars if I could. I just bought a second one for my husband.

Game changer. Keeps my sparkling water cold and carbonated all day! Does not leak. Easy to carry, clean and store. I bought two more.

Very happy. Keeps carbonation and keeps cool.

If you're on the hunt for a water bottle that can keep up with your busy life, look no further than the Ninja Thirsti! I take this sleek 24oz travel companion to work every day, and let me tell you, it’s a game-changer. Not only does it keep my water icy cold, but it also keeps my sparkling drinks fizzy for ages—like a party in a bottle! The insulation works like magic, and I’ve genuinely forgotten what warm soda tastes like. Plus, it’s leak-proof, so no more accidental "sparkling water showers" in my bag. And did I mention it’s dishwasher safe? Cleaning is a breeze—because let’s face it, nobody has time for hand-washing when there are important matters to attend to, like debating the merits of the perfect bubble-to-liquid ratio. I've bought a bunch of products from Ninja, including a suite of kitchen equipment, they've proven themselves perfect in the kitchen and on the go! Overall, if you want a reliable, stylish, and functional water bottle that holds its own against the best of them, Ninja Thirsti is your trusty sidekick! Cheers to hydration!

Excellent item, very pleased with purchase. Keeps drinks cold and fizzy.

Love this
