I love this cup
I absolutely adore this Tumblr. I love the color and how it changes throughout the cup. I love that my drinks actually stay cold, if I fill it up with ice water around midnight when I wake up around 9:00 a.m. the ice is still there. It keeps drinks cold longer. The one lid that you do have is actually spill proof. It's super easy to clean, it's super easy to use and it just kind of fits in your hand. I can easily take this to work with me if it's right in my bag and in my cup holder

Gorgeous, keeps things hot
These Iron Flask tumblers are all great quality and really beautiful. They keep water hot for hours (5 hours and counting). Love them! Well made. Nice rubber bottom to not damage the wood table. Wish the price were a bit less but I do love them in general.

Beauty and Function!
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!

Love it - but only comes with one lid
UPDATE: I ordered a second one (Pearl color), and it reinforces my original 4-star rating for incorrect description. The description is that the tumblers have a powder coating - which my first one had and I loved (Dark Night color). The second one is a non-powder coating - regular metal, shiny finish. The product write-up specifies: "FUNCTIONAL DESIGN: The powder coat exterior finish is a classic.". It also only came with one lid, while the write-up states, "2 LEAKPROOF LIDS: Yes, the Rover Tumbler comes with TWO insulated lids. A leakproof Straw Lid with 2 Straws, and a leakproof Flip Lid.". I got a great deal on it during Prime Day, so the price is right, and I'm sure I'll enjoy using it. I just wish the seller would write a description that is true to reality of what the consumer can actually expect. If it only comes with one lid, say so. If some colors are powder finish and others are not, find a way to specify that as well. Please. ORIGINAL REVIEW: I can already tell that this Iron Flask 24 oz tumbler is going to be a favorite. First, LOVE the color combination. It also has a nice feel in the hands. Keeps water cold throughout the day. If I remove the straw and engage the flip top, it does not leak when turned upside down. Haven't tried it with hot beverages yet, though. My experience with the two most common complaints in other reviews: * "Couldn't get the lid off." Unlike many tumblers, this lid is TWIST OFF, not pop off. Once I figured that out, the lid came off easily enough. The twist lid design makes it more secure. * "It only came with one lid, but the description says two lids." I concur - mine only had one lid as well. It is not worth my time to claim the second lid from the company (particularly since others have comment on their complaints falling on deaf ears). If the package had contained two lids -- OR if the product write-up had been altered based on previous complaints -- I would have given this tumbler 5 stars. However I have removed one star for the false advertising of two lids even after multiple reviews mentioning this issue. Taking the time (15-30 minutes, perhaps?) to adjust a statement or two in your product description would increase your company's credibility and trustworthiness.

My Favorite Water Bottle!
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!

Durable and beautiful
This 24-ounce tumbler is the perfect size, and the color is amazing! It keeps ice cubes from melting for hours, and always keeps my water cold. Iron Flask products are durable and well-made. I already purchased another one!

Great cup
Good travel mug. Fits well in cup holders. Keeps drinks cold and holds ice for at least 24 hours.

I was very happy when this mug originally arrived. I used it 3 or 4 times and was very excited to have a travel mug that is fully leak proof. But today I nearly poked myself in the eye while driving - black cover for the drinking opening no longer stays in place while I'm drinking. I thought I van let it go since theug is so wonderful. But it has become a hazard and I'll have to return. I'll be ordering a replacement. However, it is very disappointing that one moving part that's there is already not working properly.
