IRON °FLASK Classic Tumbler 2.0-2 Lids (Straw Flip), Vacuum Insulated Stainless Steel Water Bottle, Double Walled, Thermos Travel Mug - Midnight Black, 32 Oz

I am a nurse and I like to have coffee all day and I LOVE this mug. It keeps coffee warm for over 5 hours and the colours are beautiful. I love that it comes with 2 lids and I’ve never had any problems with leaks

Works Great, Very Happy!

I've had the 32oz Calacatta Iron Flask for a little over a month now. I never go anywhere without it. I love how long it keeps my water cold. It's very sturdy and doesn't leak unless you flip it over. But even then, it's much less than a regular cup would be.I don't have an issue with the straws like other people have complained about. I also haven't had any issues with the lid (I don't use this for coffee so I haven't used the coffee lid). The Calacatta is a smooth satin finish. It looks matte but has a slight shine that shows off the gold. It's beautiful. I also love that the 32oz still fits in my standard sized car cup holder.I fill it up halfway with ice and then add cold water. With that much ice, it usually fits about 18- 22oz of water. That ice will last up to 24 hours depending on how much you refill the water. I always refill with cold water to make the ice last longer. Keep in mind, water slushing around and frequent refills will melt the ice faster, but the water will stay cold for hours regardless.

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!
