OMG! I will never but another brand. This is affordable and it keeps the ice for so so so long! Even when its 100 degrees. I am in love with my cup. II do suggest getting a cool straw to go with it thought, comes with 2 plastic ones that are durable. So COOL though. Literally.

Fits nicely in the cup holder in my car. Easy to clean and seals nicely. It holds ice for quite a while. I love the color.

The media could not be loaded. So I have purchased about 4 tumblers from Iron Flask over the years, and I can truly say that they have never let me down. I tend to be veryyy clumsy, and any denting or issues like you may see in this video were entirely my fault. They stillllll did the job. I do see some tiny chips from when I dropped a different color I bought- Dark Rainbow, but I dropped it out beside my car on the pavement!!! So I truly expected much worse after that. 😅 So here are my main reasons for loving this brand: 1. PRICE PRICE AND PRICE!!!! My lord, I’ve never found a more reasonably priced tumbler that looked incredible AND actually outdid any other tumblers I’ve had by keeping my drinks hot/cold the longest running time I’ve seen. And not to mention, the incredibly cool fact that they give you lids for both!!!! Epic. 2. Maintaining drink temperature! As I said before, I’ve had a few tumblers over the years and I can truly say these totally last as long as they state that they will! I couldn’t say with certainty if any other brand out there can last longer or not, I haven’t tried all of them. But I do feel this one was the most stylish and versatile options included! 3. Durability! Once again, I drop everything in my life. Literally everything! I have no real ability to not spill, drop, toss, trip, or fall in my life. It is truly annoying and I hate it! But that’s why I love this tumbler. Honestly, those issues that may be visible in that video are from mannyyy different drops, more than one being the concrete parking lot 😂😂 So this baby is looking pretty freakin good when you consider that. ALSOOO- if you see my video, you may notice that Aurora Lights is an incredible matte finish! I have the rose gold as well, it was more of a smoothe plastic type feel (not sure how to word that), which was still awesome! But the matte finish, it’s so metallic and beautiful. I highly recommend this color!!!! 😍😍😍😊😊😊😊🙏🏻🙏🏻👍🏼👍🏼👍🏼💯💯💯💯

The media could not be loaded. I have been looking for a 100% LEAD FREE tumbler (verified by customer support) for a very long time. This is perfect! These things range from 14oz. to 60oz. and come in a dizzying array of stunning colors from boring to cute. I am so happy I have finally found my last tumbler. Here's to a lifetime of sustainable hydration! “Hello there, Thank you for purchasing our product! I'm happy to share with you that our bottles are 100% lead-free. There is no lead that would reach liquids by any means. We do not use any leaded materials in the process of making our water bottles. All materials used are food-grade, safe, and FDA-approved. In addition, our bottles are double-layered and vacuum insulated which means no material outside could reach or affect the interior of the bottle. No lead is also used in the construction of the Iron Flask water bottles but rather "Heat welding". Our flasks are not soldered; instead, they are molded with stainless steel and painted with lead-free paint. This includes the bottom center part of the bottles. If you would also like to know if the paint is lead-free, it is!” UPDATE: Nearly perfect. I'm not taking a star, but there is one issue with this tumbler. If you are exact with your water intake like I am and keep track of your water intake daily, I have an important detail to share with you: While this tumbler is technically capable of holding “32oz” (≈946 millilitres), you have to fill it up over the threads of the tumbler, nearly to the top of brim of the tumbler, and doing so will not allow you to put one of the lids it comes with on it. This isn't a big deal for me around the home because I don't use the lids there anyway. I use this as a giant stainless steel cup and have a pretty pink flower Daiso melamine coaster that lays perfectly on the top of this to protect the lip and contents. Somehow it has a perfectly 3D printed inset of a few millimeters that fits into the tumbler exactly so that it can't slide around or off the top of the tumbler when I'm walking around with it and jostling it throughout my day. This serves the purpose of a very low profile, slim lid that keeps dust out while not in use. But if I go out on a hike and buy two bottles of water to consolidate into it as intended, they're not going to fit and will overflow when I try to screw a lid on. Filling this up to the threads only gives you 839ml of water as opposed to a full 946ml. So you'll have to chug that remaining 107 before trying to use one of the lids it came with. Again, it not being an exact 946ml/32oz. with a lid probably won't be an issue to most people, but I purchased this for hydration tracking and so I could know that I just need to drink 3 of these in one day and I'm done with my water intake. I really didn't want to worry about drinking three of these and then breaking out the scale to measure the remaining change of 321ml that adds up to I need to hit my hydration goal for the day. Again. Not too much of an issue because I can just fill this up and drink to the threads if I need to take it out of the house with a lid, but just be aware, if you are just filling this to the threads, you are not drinking “32oz.” a tumbler and this will add up to missing out on 321ml of missing hydration a day. So just a heads up, if you think you can put 32oz. into this and use the lids, you can't. So just fill it to the brim and drink enough out to use a lid if you need exactly 32oz. of water.

If the actual amount of what you are drinking is important (for example I've been told to drink so much water a day) this is not a good measuring device. It is not 24oz. At best it's maybe 18oz - a 16.9 basic water bottle almost fills this cup. It is spill resistant not spill proof. It keeps things cold for long periods of time. Love the feel and size of it. Be extra careful to clean the lid - specifically the spot around the straw hole on the underside - take a q-tip to it to really get the liquid out otherwise it will grow stuff. Love the fact that it comes with different lids, easy to clean, transport. Would recommend but watch out for those lying ounces.

This is my second Iron Flask product. Last year I purchased a gorgeous (dark rainbow) 32 oz tumbler with the clear lid. I go through water faster than the ice can melt, it's incredible. It's my go-to way to drink water at home. I wanted to get something designated for iced coffee, so I chose the 24 oz (aurora) tumbler with the black lid. Wow. Again, the color is gorgeous, the ice takes forever to melt, and the choice of 2 lids and inclusion of 2 straws is really great. I thought I would gravitate toward the straw lid, but the flip lid is really nice. The way it presses close feels secure, but not abrasive (no hard snap), and it's slightly lowered section where the sipping hole is feels really pleasant when you're having a drink. It's hard to explain, but "pleasant" is really the best way to describe it. Highly recommend this brand.
