    • I love this cup
Style: 24 oz - Solid Lids Color: Dark Night
This cup is great! It’s solid, well made, and beautifully colored. It comes with two different lids and they are really thick! I’ve only used the lid for the straw. It keeps my drink cold overnight. The only thing I wish was that I had bought the bigger cup.

    • Checks every box. Genius design!
Review Image by Tammy Daniluck Tammy Daniluck
It’s made from quality steal. The lid with the small hole & straw is thick to keep it cold and has ONLY enough room for the straw in case you tip it over. It is doubly awesome because that straw hole is small enough to allow me to easily put my finger over the hole and shake up my drink when I use a powdered drink instead of stirring with a spoon (doesn’t work well) or using the other top to shake it when I want to use the straw top. The other lid (flip top) is also well made and has a fairly small sip hole which also prevents BIG spills and can also be used with the straw. I haven’t had any leaking from the flip top lid or from any of the seals around the edges. It is metal and if you dented really badly that might prevent a seal. I love the outside surface- it’s beautiful and it has a matte surface so it will NOT easily slip in your hand and it does not have any condensation from icy cold beverage inside. This is one of my FAVORITE purchases ever from AMAZON- I rarely review anything and I do not give fluffy slanted reviews- if it’s good exalt it. If it’s bad, I burn it to ashes.

    • Never going back to any of my old brands of tumblers!!!!
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!!!! 😍😍😍😊😊😊😊🙏🏻🙏🏻👍🏼👍🏼👍🏼💯💯💯💯 ... show more

I bought 2 of these mugs 20z and I am very happy with them. I accidentally dropped one and lid for not break. That's a big plus since I broken so many lids. This one holds up well and is nice and comfy to grab. Non slip and bottom of mug is a nice soft rubber. Must have for a coffee drinker and coffee does stay hot for about 4 hrs depending on where you are weather wise of course. ... show more

Great product, I ordered 6 for our family vacation. Each child got their own color. Kept our beverages cold while at the beach. Excellent value for the price.

    • Finicky, but worth it.
I love Iron flask, when it works properly. It really does a great job keeping things hot or cold, amazing insulation. But the lid is finicky and I have to do a leak test every time I screw it on. I have two of these flasks, and they behave the same. Just being honest, it's a great thermos, just have to work around the finicky seal. ... show more

    • Indestructible and keeps liquids at a great temperature
Review Image by Amazon Customer Amazon Customer
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. ... show more
