Without a doubt, choosing the Iron Flask was the best decision I've ever made! I was on the verge of purchasing a Stanley, but I am beyond thrilled that I opted for my stunning 40oz Iron Flask instead. It’s truly an incredible product! One of the standout features is that it comes with not just one, but two delightful straws, along with two fantastic lids that offer versatility for any occasion. I chose the mesmerizing Aura color, and let me tell you, it is absolutely breathtaking! This tumbler is remarkably durable, built to withstand the rigors of daily use, and I can easily gulp down a significant amount of water without any hassle. To my surprise, it's surprisingly lightweight, which makes it comfortable to carry around wherever I go. There was one moment when my mom accidentally knocked it over, and I held my breath, but to my delight, there were no spills or leaks! Just last night, I filled it with ice-cold water right before I went to bed at 9:30 PM, and when I woke up at 6 AM, the ice was still intact, and the water was perfectly chilled. Money well spent! I am going to be grabbing more of these amazing tumblers! I can sincerely say this has been the best birthday gift I’ve ever treated myself to! 🎉

Got deent price (much cheaper than the "popular" brand version) on the first one (pink). I liked it so much I had to come back and grab a 2nd one (yellow), and got even better price on that. I got 32 ounce size on both. As pic shows, each comes with 2 straws, a lid to use with straw, which is a screw on, solid lid. (Other brands have lid that looks cheap, like the lid from sour cream or somethinhg). It also comes with a flip top lid for use without straw, like with coffee or other hot drinks. Both lids screw on and are very secure. If you close tightly, it's almost impossible for it to come loose. It keeps my water cold a long time. It's wide enough to get my hand all the way to the bottom inside for cleaning it, which is a great feature. Even water bottles can get funky, so glad I can clean more completely. While it is wide enough for cleaning, it's not top heavy enough to easily tip. And the bottom is narrow enough to fit in most cup holders. Great design, and excellent features and quality. I very highly recommend this mug / bottle and would absolutely buy this brand again.

I love that this is durable and keeps my drink cold . This is the best cup I’ve had , lid is secure , comes with two different tops and two straws.! Reasonably priced

Love, Love, LOVE! I don't write reviews often, but when I do, it's because I'm inspired to do so, and this new mug has done it! First off, it's gorgeous! This blue-ish/purple color is so cool, blends together so well (appears to almost change colors at different angles), and it's metallic looking! It comes with two long straws which I really which I find easy to drink from! I was pleasantly surprised about the feel of the mug because it's super smooth all around, the handle is so comfortable and very sturdy feeling! I love how it came with two different lids to use either with a straw or drinking straight from the mug with a flip up lid. It even comes with a motivational sticker that I put on my mug too and says, "You Got This". I've been trying to drink more water in the New Year and my new mug has inspired me to drink more water every day since I've had it so it's already working! Highly recommend! Update: After using it for a couple days, I'm even more amazed! It truly keeps my drink much colder for longer than I've ever experienced before. I also forgot to mention that I really like how the bottom of the mug is rubber, so it has a good grip and won't slip easily. 11/10! Great product, worth every penny!

Disclaimer - I haven't tried the straw lid yet, just the flip cap lid. This is a great tumbler. It fits in the cup holder, truly doesn't leak, keeps drinks cold (particularly if it was cold to begin with or has some ice in the first drink of the day), and the color I got (Aurora) is so pretty. I'm even going to buy another one to keep one at work and one at home. I do have one problem with it. It's a righty mug, and I'm a lefty. It seems like such a silly thing, but it makes a difference! Because I'm a lefty, I usually lift my mug with my left hand, which also allows me to drink my water while I'm working. But to now have to drink with my right hand means I have to stop what I'm doing. It's so silly but it interrupts my flow! (And no, you can't just screw on the cap differently to make it a lefty mug.) Luckily this is solved just by not using the handle while I'm at my desk, but it is a minor annoyance. Not enough to keep me from buying another, though!

Love this cup. It's the second one I bought. The lid is perfect and keeps all the liquid inside the cup, even when my toddler gets ahold of it to steal my drink. Keeps my drinks cold all day. (I haven't used it for anything hot yet). The straw is the best part. It's a flexible, durable plastic. I don't have to worry about it breaking with sharp pieces if it accidentally gets bent. The handle makes it easy to carry when I'm carrying a bunch of other stuff and it fits in my cars cup holder with no problem.

I love this mug. I ordered the 40 oz Auroa style. This mug keeps ice solid and water ice cold for 24 hrs. I have a bad habit of dropping and spilling, this mug has proven to be a game changer. Doesn't spill at all with the straw top. I haven't tried the other lid because I prefer cold drinks. This mug was totally worth the money and it fits in my cup holder. I want one in every colour. But this exceeded my expectations. It's also dishwasher safe which is a HUGE bonus if you hate washing stuff by hand. Best mug I've bought. The Aurora colour is so beautiful my picture doesn't do it justice. It does get hand prints on it if I don't use the handle but they wash off easily with a damp paper towel. I recommend this seller and it comes with a warranty that you can easily register in 5 minutes online.

This cup has been fantastic. However, after 4.5 months it now leaks from the seal at the lid. And I mean it leaks A LOT! I would like to reach out to the company to see what they can do but have not found a way because I’m outside of my 30 day return window. It’s really disappointing that it lasted such a short time.

My coffee stays hot all day long and I can almost fit the entire pot in this 40 ouncer. I also have the 30 ouncer but it’s hard to hold without the handle. Get the ones with the handle!

Es perfecto! Excelente tamaño, color justo como en las fotos, gran calidad y conserva mi agua helada por días! Es mi quinto producto de Iron Flask. Recomendado!!

I love this and use it daily. I love that it comes with two different lid styles and two straws! And the quiet base is a bonus. I haven't kept drinks in it for more than a few hours (maybe 8 at the most), and so far I've only had cold drinks, but it keeps them cold so well that I now use far less ice in my drinks. It promises not to spill, and, clumsy oaf that I am, I've knocked it over several times - no spills. So I'm a very happy camper, and can highly recommend this. I've bought several other brands before, including that fashionable one that costs twice as much, and it measures up. My other half is very envious as he loves the colour, so I'm thinking I might have to get another one and give this one to him.
