very beautiful, useful, solid and convenient
I bought the product because it is steel and can be opened with one hand. I will keep the water in it for a long time to use it in emergency conditions, I hope there will be no corrosion.

can take a hit. Keeps warm and cold.
i have been using this product for nearly 3 years now and its fallen and bumped so many times. there are multiple dents on it. However, the bottle is still perfect. Its one of my best decisions and I am looking at buying a different color to replace my old one. Quality of material is amazing! love this bottle and definitely recommend to anyone who is looking to buy a long lasting one.

Super happy for order! Dream come true!
Aside from delivery delay issue, I super like what I’ve purchased! I happen to have had a comparison from an item I previously ordered (name drop: #water), it was delivered broken so I have to return the item. But with Iron Flask, from the box to the item - thumbs up! The box is still intact, I love the color I selected, there are 3 lids to choose from (can’t pick which one though (๑˃̵ᴗ˂̵) ) - all lids are super nice, there’s one lid that you can put a strap/chain on it. I can store a liter of liquid - I don’t have to make a refill for several times a day! There’s also a lifetime warranty against manufacturing defects. I desired to have one of this kind of drinking bottle and now I have it through Iron Flask! And I like the brand name as it is somewhat congruent in my real name! I just wish that, since the instruction is handwash only, the mouth of the bottle is wider, so I can get my hands inside the bottle to rinse/wash it properly.

Die Flasche gefällt mir optisch sehr gut und ist von der Anwendung her perfekt. Ich transportiere damit auch Flüssigkeiten die Kohlensäure enthalten. Funktioniert gut - man sollte aber den Nippel zum Trinken langsam hochstellen und vorher nicht unnötig geschüttelt haben. Die mit 18 und 22 Oz ( 530 und 650 ml) sind für mich am besten geeignet da man sie mit einer Hand umfassen kann und sie passen in die Autohalterung.

This insulated water bottle is a fantastic all-in-one solution for staying hydrated on the go. The stainless steel double-wall construction keeps drinks cold for hours and hot beverages warm without condensation or heat transfer to your hands. I tried both water and tea, and the temperature retention is impressive. The bottle comes with three different lids—straw, flip-top, and screw-top—so it’s easy to switch depending on your activity, whether you’re at the gym, commuting, or hiking. The straw lid is convenient for sipping without tilting, and the flip-top is secure and leak-resistant. Build quality is solid, with a durable, easy-to-grip exterior and a wide mouth that makes cleaning and adding ice cubes simple. Available in multiple sizes, it fits comfortably in most cup holders and backpacks. Overall: A highly versatile, well-built water bottle that combines practicality with style. Perfect for anyone looking to keep drinks at the ideal temperature throughout the day.

This was like my favorite water bottle for months. It kept my water ice cold and I loved the gold. I didn’t even care if it was too big for my cup holder. To the person that stole it, I hope you’re taking good care of it 😔
