Ninja DW2401MT Thirsti 24oz Travel Water Bottle, For Carbonated Sparkling Drinks, Colder and Fizzier Longer, Leak Proof, 24 Hrs Cold, Dishwasher Safe, Stainless Steel Insulated Tumbler, Seafoam Blue

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.

Perfect bottle to keep your Ninja drinks ice cold for longer periods of time. I purchased the 18 oz. model which is the perfect size as it fits into most cup holders. The handle is great for carrying along on hikes. It is easy to use and easy to clean. Typically, drinks with ice will still be very cold after 10-12 hours. It is leak resistent; however, liquids sometimes pool around the drinking spout which leads to spillage. Several of my family members also have these. I purchased the gray model but it comes in a variety of other colors. Highly recommend!

I love this water bottle. I prefer seltzer to water and this bottle keeps my seltzer fizzy. It stays cold a long time and the bottle is very sturdy. Excellent!

Keeps my carbonated drinks cold and fizzy for a long, long time! Place it under your Ninja Thirsti, make your desired beverage, and away you go! The attached strap makes it easy to carry and it's slender design allows you to place it right in your car's cup holder.

Works great meet expectations.

I like this bottle because the fizz stays in your drink. Convenient carry handle and it definitely keeps your beverages hot or cold.

I have been waiting for something like this for probably 30+ years. Or at least since stainless steel water bottles have become super popular. I am undoubtedly a Diet Pepsi connoisseur for 30+ years. I hate nothing more than warm nasty soda. I just happened to come across this little miracle while playing around on line. It was like the clouds opened up and I heard "aaaahhh" and it was amazing! I had to hurry up and buy one and waiting the 3 days to receive it was torture. Finally the day if arrival. I unpack it lovingly, wash and dry it. I get started on my DP pour into my magical new bottle that promises ice cold soda for 24hrs. This is AMAZING. It works just as stated and the carbonation is handled perfectly. No more carbonation hitting me in the face when I tried to make just stainless steel bottles work. If you are like me and love carbonated drinks, this is a must have and worth every single penny!!!!

Keeps the fizz in fizzy, and cold for 18 holes of golf + in Palm Springs @110 f
