Customer reviews

Absolutely love it
I purchased one of the 1.2ltr mugs in the Aurora design. I read many reviews first, and decided to try and add to my ever growing collection of travel mugs. Before officially using it, I decided to put it through a couple days of tests, first. DESIGN It looks good, is a good size, and so far I have found nothing of concern. I haven't had opportunity to check it's size in a cup holder, yet, but it appears like it should fit. Also a good size for cleaning without any issues. LEAK PROOF: CLOSED LID - I added a basic mugs worth of water in, fastened the lid, and held the mug upside down. Not a single drop. I shook it, and tipped it upside down again. Still no leaks. I then filled the mug entirely, and did the same thing to see if the volume of water made a difference. Result: still leak proof. STRAW LID - Obviously, given the design and function of a straw, when the straw is inserted it means it is not leak proof. Without inserting the straw, I tried the same tests, and while there are is some leakage, it is very very minor and a slow drip. Therefore, if the mug tips without the straw inserted, you have plenty of time to correct it before there is any significant loss of liquid. The mug also comes with two sturdy, but not entirely inflexible reusable plastic straws. SMELL/TASTE: All food/drink containers tend to smell or taste funny when brand new. I found that by doing my early days testing, that issue was non existent by the time it came to actual use. HOT DRINKS: I filled the mug with freshly boiled water, and tightened the lid. Every couple of hours I would pour a small amount into a bowl and dip my fingers to test the temperature. Doing this also meant that there was space for air to effectively cool the rest down a little quicker. That said, after a brilliant 13 hours, I still had very hot water, which satisfied my curiosity. I probably should have left it longer until the water actually cooled, but I personally wouldn't keep a hot drink for that long anyway, so it was more than enough for me. **Edit to add: I forgot about my drink one day, and it was still of a nice warm drinkable temperature after 24 hours. Absolutely thrilled. COLD DRINKS: I filled the mug with cold water, and added three good sized ice cubes, and tightened the lid. As with the hot water, I checked every couple of hours. The ice cubes melted within a couple of hours, but that wasn't a big problem for me - it made sense given the rest of the water was already of a warmer temperature. However, after 24 hours the water was still nice and cold - not necessarily ice cold, but absolutely cooler than lukewarm and still nicely refreshing. Due to disability I don't venture out too often so have yet to comment on it's ease of carry, but using it around the home is easy enough and I absolutely don't foresee any problems. Similarly, durability can't be judged as yet as it is still rather new to me. However, all in all, it is a fantastic product and great value for money. I am hoping to purchase more, in time.

Great Vessel
I recently bought a nice water filtration system which has allowed me to completely ditch plastic water bottles. I wanted a replacement for my normal 1L glass mug and found the 40oz Iron Flask. True to its description, this insulated mug does a great job at keeping cold liquids cold. I haven't tried with hot. If I pour refrigerator-cold water into this mug in the morning, it will still be at the low end of cold into cool in the evening. I can imagine even if I had the same water in their for an entire day, it would still be cool. I prefer my water ice cold, so this mug works perfectly for me since the water never lasts long. The mug comes with 2 lids. One has a hatch lid for sipping, and the other a simple hole for a straw (2 straws are included). My wife has gone through +10 water bottles over the years and she ditched her newest fave for this one after seeing how simple the lids are for cleaning and use. Another great aspect of this mug is the weight. Even completely full, this mug is very well balanced and easy to carry for both my wife and I. These mugs look cool too. I chose the black with white speckled and my wife chose the blue/dark blue gradient. Both have a great look and feel. The coating isn't rough at all. I would feel zero shame in bringing one of these around while running errands. Overall this mug exceeded our expectations and is highly recommended!

Amazing cups and fantastic customer service
I love Iron Flask Copilot cups! I like them even better than my expensive Stanley cups, and I find the Iron Flask cups keep my cold drinks cold longer than my Stanley. I can put ice in it in the morning and the ice is still there all day. The price is great and the quality is spot on. I’m a vet tech and I call my cup my “emotional support cup.” Even other techs I work with have bought them. Their color options are great as well! Their customer service is amazing as well. The cup I just purchased had an issue with one of the lids. I contacted them and they quickly responded to address the issue. Out of all of the Iron Flask cups I have, this cup was the only one I’ve had any issues with and they quickly helped me out with it. Highly recommended!
