IRON °FLASK Classic Tumbler - Vacuum Insulated Stainless Steel Water Bottle, Double Walled, Drinking Cup, Insulated Travel Mug (Stardust Unicorns, 12 oz Kids)

IronFlask makes the most high quality, prettiest and durable water bottles! I use this one at home next to my working computer and it makes it so convenient and easy to stay hydrated during the day. I generally like drinking cold water and this bottle does a great job to maintaining it cold for the entire day even the day after even WITHOUT ice! Finally, I look forward for bottles without small hinges or gaps that makes it a pain to clean, and this one is perfect with its simple and clean design. 100% recommended!

As you can see I have the 40oz which is my water cup, I had a Stanley but with two large dogs and being clumsy it got pretty banged up in the four months I had it, but my IronFlask cup has survived all of the same abuse and still looks brand new. My 24oz cup I use for iced coffee or smoothies, and when I say it keeps my drinks COLD it keeps them COLD. I can put ice in my water cup in the morning and most of it will still be there by the end of the day even after refilling. My 20oz is strictly for hot coffee and tea, it keeps it super hot so I usually have to keep the lid off for a few minutes before I seal it up and go.Overall these cups are my favorite of all time. I have used Stanley, Hydroflask, and Yeti but none of them can compare to these cups. I wouldn't say they're 100% leak proof but I definitely have to turn the cups almost upside down for any leakage. Zero scratches, zero dents, the newest cup is my 24oz, oldest is 40oz.I love all the colors but I have to refrain from buying all the cups. The size range is phenomenal compared to Yeti who supposedly has the best sizes (WRONG). And the rubber grip on the bottom is a life saver, I don't have to worry about a tail hitting the cup and it sliding AND tipping over.Overall these cups are solid, reliable, and do not disappoint.

I received my 32 oz. "Dark Rainbow" (pretty!) IRON °FLASK tumbler yesterday and feel compelled to write this review to encourage you to get your own NOW! I live in the sultry south where heat and humidity will turn your ice-filled glass into a watery drink within minutes. Initially, I bought this to use as sort of an "individual" ice bucket so I could refill the ice in my glass of tea without getting up every five minutes of a Prime-binge, especially any compelling thriller. Indeed, for the first night of having this beauty, that is precisely how I used it—and it worked perfectly. At the end of the night, I left ONE lone ice cube in the tumbler to see how it would fare. Twelve hours later, that solitary ice cube is only partially melted and still icy cold! The tumbler itself comes with two straws, and two lids: one for use with a straw and one flip-top for use with hot drinks (or if you just prefer to drink directly from the tumbler). Each top is very thick—I've never had a tumbler where the top is designed to also provide insulation. All-in-all, I am very impressed with the quality and functionality of this tumbler. I only write reviews when I am deeply disappointed with a product to serve as a buyer-beware herald, or am over-the-moon pleased and what to provide fellow shoppers to confidently purchase. Happily, this tumbler is the latter.I haven't tried it in my car's cupholder as yet, but believe it will easily fit there as well. Also, there was ZERO condensation when the cup was filled to the brim with ice and none when I checked that solo melting ice cube this afternoon. I love that I can place the cup on any surface without worrying about damage to the finish.NOTE TO MANUFACTURER: I still would like to find a mini-ice bucket (48-50 oz. would be ideal, and not more than 5" diameter) to use when I just want to drink from a glass, and don't want to haul out my big ice bucket. I am convinced that YOU are the manufacturer to create the perfect mini-bucket for a chair-side refill. I would gladly be your first customer. Thanks!

I decided to upgrade from my plastic freebie bottle and opted for the IRON °FLASK Tumbler, and I couldn't be happier with my choice. Not only did I want to feel more cool and luxurious, but the fact that it came in my favorite color, green, was a fantastic bonus!From the moment I received it, I was pleasantly surprised to see the metal interior of the tumbler. The construction feels solid and durable, which gives me confidence in its longevity. I've taken it along on hiking trips, sometimes even running and jumping, and I must say, it has exceeded my expectations. Not once did it spill a single drop, even while stored in my backpack alongside important items like my art sketchbook and reading books. The design of the tumbler truly deserves appreciation for its functionality and reliability.Not only does the IRON °FLASK Tumbler impress with its performance, but it has also allowed me to make an impression on my friends. They have been impressed by its sleek design and the fact that it keeps my drinks at the desired temperature for extended periods.In summary, I wholeheartedly recommend the IRON °FLASK Tumbler to those seeking an upgrade from plastic bottles. This tumbler offers a cool and luxurious feel, especially with the added benefit of coming in various attractive colors. Its metal interior provides durability, making it suitable for outdoor activities without the worry of spills. The tumbler's design and functionality have left a positive impression on both myself and those around me. Don't hesitate to try it for yourself and elevate your hydration experience.

After over a year of daily use, I can say that this is *almost* the perfect tumbler. No leaks, no sweating, fits every cupholder I’ve encountered, and it keeps beverages cold for many hours. I go to bed with ice water and it’s still full of ice in the morning. My only complaint is that the lid can often be very difficult to open.
