5.0 out of 5 stars Keeps it hot!
Reviewed in the United States on August 25, 2024
The Iron Flask coffee mug is a game-changer for my daily coffee routine. It keeps my drinks hot for hours, and the double-wall insulation is impressive. The design is sleek and durable, making it perfect for commuting or traveling. The lid fits securely, preventing leaks and spills, and the wide mouth makes it easy to clean.

I also love the non-slip bottom, which keeps the mug steady on surfaces. The handle is comfortable and well-designed, making it easy to carry around. If you’re looking for a reliable, high-quality coffee mug that maintains temperature and is built to last, the Iron Flask is an excellent choice. Highly recommended!

5.0 out of 5 stars I finally found my mug!
Reviewed in the United States on March 20, 2024
I have been looking for the perfect coffee mug for a long, long time. At Christmas, I was hopeful when I bought the Permula 16 ounce coffee mugs from QVC, but that was a major disappointment. Its 16 ounces was filled to the brim with no room to put the lid on. And they didn’t keep my coffee as hot as advertised. The final straw was when the color started peeling off.
I think I read reviews on most of the coffee mugs with lids and handles here on Amazon before settling on Iron Flask. I’m so glad I did. I chose the 16 ounce so it would work with my Keurig K-Cafe (you do have to remove the cup holder). I make my coffee extra hot, and so far, it stays hot about four hours. I made a cup and just sipped it over that time frame to see how the mug did. It’s easy to clean by hand. I just use Dawn Power Wash spray and hot water and it only takes about two minutes to clean it. The lid can go in the dishwasher. The handle is really comfortable, and it’s a nicely balanced mug. This is the first mug I’ve found with an insulated lid, and it’s also spill-proof. It has an awesome built-in rubber coaster on the bottom that protects any surface you put it on.
I got the black marquina color which is a rich, beautiful, black and white marble color. I highly recommend.

Bought two of these on a flash deal....and will continue to buy more! They keep things at whatever temperature you want. The lid is super durable and does not leak. I literally dropped one of these from my bike onto blacktop...and although it got a little dent on the side, it didn't even pop open or spill. I still use it. This one is a little bigger than the last one I bought, and it's perfect to take to work...fits beautifully in the cup holder and easy to carry.

5.0 out of 5 stars My search for a perfect mug is finally over!!
Reviewed in the United States on September 18, 2022
This is my 4th generation coffee mug and hopefully the last one for a long time. I’d been on an endless perfect coffee mug search for a few years.
First one was contigo 16oz leakproof thermo. It was pricey at $25. I liked it for about a year but it didn’t have a handle. Also I like to put a lot of milk in my coffee, so milk solids got stuck in the very complex leakproof mechanism. It stunk really bad if I did’t breach it once every week.
Second was Tal 17oz mug from Walmart. It has handy handle and price was right at $13 but it was too tall and didn’t fit under my instant solo coffee maker no matter how acrobatically I tilted it.
Third was Sursip 24oz around the same price on Amazon, it was short enough to fit under the said coffee maker, but then it was too wide to fit inside my car cupholder. Do you know how annoying it is to have a coffee mug that doesn’t fit into a cupholder but is not leakproof? Also this one had a flimsy lid that broke in about 2 weeks.
I almost gave up trying to find a mug that fits all my specifications. Not to mention buying so many reusable-but-not-biodegradable-mugs completely defeats the whole purpose of being able to reuse them…
Don’t judge my ecological consciousness, because I finally found THE ONE!!
Enter Ironflask 16oz mug, my absolute perfect mug. It’s not the cheapest but half the price of Hydroflask or Yeti. with its shiny pretty coating and a handle, there’s a built in coaster at the bottom. This prevents me from carelessly knocking it on something and denting the bottom, messing up the integrity of the vacuum seal. The bottom coaster ensures that your drink stays cold/hot for a long time. It is juuust short enough that it perfectly fits under my instant solo coffee maker. ( see picture)
Unlike my 3rd mug, the ironflask lid is sturdy and well designed. It is a silicone lined screw-on lid that goes around about 1.5 times before it is finally sealed tight, where the opening stops right at where I want to sip from, exactly 90 degrees left from the handle, because I’m right handed. If you’re lefty, you’d have to learn to drink your coffee with your right hand, sorry. But anyway, the lid is simple enough I can get all the milk solids out with a dish sponge and it won’t stink later. I tried to check how “leakproof” it is by holding it upside down. It did drip a few drops of my coffee but I’m fine with that. I only need it sealed enough to commute to work. It really does keep your coffee hot or cold all the way to work then a few hours after.
Oh but please note. It’s NOT dishwasher safe. Not to me, but it might be a deal breaker for some. I don’t even own a dishwasher so it works for me, but if you’re looking for dishwasher safe coffee mug, keep looking.
Also I hope everyone knows but it’s also NOT microwave safe, dang!
So over all not too many cons while pros adds up sky high with this mug. I’m contemplating about buying another one, so if I happen to lose it or something I will still have my perfect mug.

4.0 out of 5 stars Keeps things hot...tough to open.
Reviewed in the United States on March 15, 2023
Overall, I like this mug. I don't know that I would order another one though. Maybe just my mug is difficult to open?

Pros:
Keeps things heated: Left my mug in the car on a cold winter day. Came back during lunch break a few hours later and my coffee was still warm! Not hot, but warm enough to enjoy.
Leak proof: I have yet to see any leaking at all. Very tightly sealed around where the lid screws on and the mouth piece.
Slip proof bottom: stays put where you put it down.
Ombre coloring: I like the colors of the mug (I have a light blue one) and I haven't had any chipping or fading. Granted, I haven't dropped it or put it through any real paces.
Fits in my car cup holder snuggly.
Handle is nice.
VERY easy to clean!

Cons:
Lid is difficult to twist off. I love that this is leak proof. That said, it takes some strength and sometimes the use of opening the mouth piece cover to use as leverage to twist off the main lid. Especially not easy if your hands are wet from washing other dishes before getting to this one.
Mouth piece cover is very difficult to flip up. I cannot use one thumb to open the lid. I need to use both thumbs to pop it open. Again, it's part of the leak proof bit, but it's very difficult to open.

While there are a lot of pros for this mug, the cons are pretty significant. I will continue to use this mug because it does keep things hot/warm and it is very good at being leakproof, but I probably won't buy myself or anyone else one of these because they are so difficult to open.
