IRON °FLASK Grip Coffee Mug - Leak Proof, Vacuum Insulated Stainless Steel Bottle, Double Walled, Drinking Cup Thermo Travel, Hot Cold, Water Metal Canteen, 16 Ounces

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.

So far this has been leakproof, even when holding upside down, as long as you've screwed on the lid entirely - you'll know if you have because the sipping opening will be at a 90 degree angle to the handle. Beware, because it is airtight, it will POP when you first open if it's a very hot liquid inside. I favor this style of sip-opening because there's no crevices that are impossible to clean like there are on the slide style openings.This mug fits the perfect diameter sizing in that it's large enough to Aeropress directly into, and large enough to be a stable base to Aeropress into, but still small enough to fit into all the car cupholders I've encountered so far. The handle is high enough that it does not interfere with putting a car cupholder.I only knock off one point because the thread is single start thread, so you can only screw the lid on so the handle faces right after it's tightened, and I'm actually left handed so that's a bit inconvenient.... But I mostly got the handle so I could carabiner this onto my belt at renfests and such, I can hold the mug the old fashioned way for daily drinking.

The mug is well made and light. Iron Flask is probably my favorite drinkware. That being said the lid on this mug screws in so you cannot reposition it to use the handle with your left hand. I'm right-handed but I drink my coffee while working on the computer which means my right hand is occupied with the mouse/trackpad. On top of that, I don't know if the lid designers have ever actually used the lid but the black piece that flips back to open the drinking hole is seriously annoying because it does not lay flat against the lid. That means the piece that fits into the drinking hole to make it leak-proof (which I have not really tested) pushes against the tip of my nose while I'm drinking. This is an unfortunate issue with many travel coffee mugs. I do have a lid from a previous coffee mug that I can use but I wanted to try this one to see if it has been redesigned to make using it more comfortable. Nope. I'll be using the lid from a previous mug that has no piece that makes it leak-proof. If I could figure out a way to remove the black piece altogether, I'd do it since I don't take my coffee anywhere other that from the kitchen to the bedroom. One really nice feature is that there is rubber on the bottom of the mug so I don't have to worry about marking up any of the surfaces that it stands on. The handle is also large enough for men who have huge fingers/hands.

I like the size, keeps coffee hot to warm for around 4 hours but it doesn't fit my standard (Seat Leon) cup holder so always worried about it falling out. It goes in about 0.5cm so just enough but far from secure.When it has tipped over it is leak proof so that's a bonusOnly right handed... Cannot change the way it screws up to put handle on other side

I ordered this mug based on the great reviews and have not been disappointed. It is absolutely water tight and keeps my tea hot for a minimum of 4 hrs. I think the small size is not very small so you get a generous amount of hot beverage and the mug is very handy to carry around. Very happy with this purchase, hoping it will last me long. P.S. The aqua-teal colour is absolutely gorgeous.

Honestly I have gone through several travel mug and this is hands down the best so far.Sturdy, leak proof, easy to clean, attractive.Its Honestly my favorite one and will be buying more

large thermal mug, this is the best one of these I have had yet, very happy with this purchase. Will buy another for sure.

I wanted to cut down on take away coffee and I wanted a new cup that specifically had a handle (I like a proper mug). This was a perfect fit and better quality than I expected. I don’t care about colour normally but it’s very pretty too! Just wish it was dishwasher friendly but no big deal….. better for the environment anyway!
