Exactly What I Was Looking For
This Iron Flask 40oz insulated water bottle was exactly what I was looking for. I work in public safety and am not always near the station to refill my water bottle and wanted something that would allow me a couple refills but keep the water cold until I needed it. This does exactly that. I used a 20oz shaker bottle as a water bottle, so this gives Iron Flask bottle gives me two refills until I need to fill it up again. It is the perfect size to keep on my passenger seat without taking up much room at all. I have not had any issues with the bottle leaking and it is very good quality. the bottle came with three different lids. One is just a standard lid that stays attached to the bottle when unscrewed and is stainless steel. There is a straw lid, with a silicone straw that goes into the bottle and a plastic straw on the plastic lid for drinking. The third is a plastic lid like a standard coffee thermal drinking lid. I have only used the stainless steel lid as I only use this to hold extra water to refill my other water bottle since I add a water flavor to it. All three lids have a handle source for easy carrying of the water bottle. I drop this thing all the time and it still holds up really well. Of course it is going to scratch or dent when you drop it, it isn't a magic water bottle. But it has not affected the lids or seals in any way. I like to put stickers on my metal water bottles anyways, so nothing a fun sticker cant cover up! I do not put hot liquids in this water bottle, so I cannot speak to how well it keeps liquids hot, but it keeps my water nice and cold so I wouldn't have any doubt in its ability to keep liquids warm for as long as it says. I would purchase more of this product in the future if I needed.

Great for everyday use.
I use this water bottle every day. Its quality is great, and it keeps my cold drinks cold for hours at a time, and it costs half the price of other name-brand bottles.

Almost 6 years and it's still going strong!
There's really nothing to say about this flask except it's top quality and it keeps my water cold all day. I've had it for almost 6 years and it's still clean and sturdy. The lid is a twist on or off kinda lid, so it works. The lid sip top is twist as well, so you don't have to worry about leaks. I managed to snag the 16 fl oz size, which holds exactly two bottles of water. And although it works, I kinda wish I went down a size. There is no straw, but the lid does come with an attached handle, for anybody out there wondering. Lastly, it's made of some real strong steel, so be careful not to drop it on somebody's head. I highly recommend this bad boy if you're in the market for one.

Got two identical bottles: one is 10/10, the other sucks
I ordered two of these after a recommendation from a friend who has had his Iron Flask for many years and loves it. I got a black one for my husband and a hot pink one for myself. They each came with different mouth piece options which is a nice touch so you can get exactly what you want (I’m a straw girl). My only complaint is this: I think my pink one is defective. The black one holds ice for days, does not leak, keeps things at temp as it should even when it’s just cold fridge water without ice, it’s a 10/10 water bottle. The pink one will melt full of ice within a few hours. It is incapable of keeping anything cold for more than an hour. The pink one condensates on the side when it has a cold drink in it and gets everything around it wet - the black one does not at all. The pink one leaks when tipped on its side. It’s very frustrating because we both use our bottles frequently and usually at the same time (e.g. beach vacations, soccer games, yard work, etc). I find myself stealing his to use when he’s not or we just end up sharing his because my water gets warm. I originally bought this for giving birth to my second baby to have ice water on hand at all times during unmedicated labor and birth (it ended up leaking all over me because I couldn’t sit up all the way to drink so I ended up drinking out of a room temp regular plastic bottle, talk about an annoyance!). I knew my husband would want one so I bought him one as well. I’d like to get another one, the pink makes me very happy. It’s a bummer because this current one I have will likely just go to Goodwill because we’ll never use it. Feels like a waste of money. I’m pregnant with baby #4 now and we’re in a heat wave so I’ve been toting my husband’s bottle around with me everywhere to help me stay hydrated and cool chasing around my three littles. All in all - a really great bottle that hits all the marks and will last forever if you don’t get a dud! I’m not sure how frequently one like that goes out but hopefully not often!

Keeps cold for awhile!
I really like this water bottle. It doesn't leak, it's easy to open and keeps my water cold For two days. The only bad part is that of course it's heavy because it holds so much water but I love having it near my bed at night or I've even left it in my car and it was still cold then next day. For the price I think it's worth it. Especially if you are trying to reach your water goals. The opening is large enough to easily add ice and my liquid iv packets.

Literally can't go wrong with this.
Best, best water bottle, especially for water guzzlers and athletes. Once you fill it with ice, that ice lasts through multiple refills for a little over two days. My bottle has survived multiple drops and bad falls, and performs great still, after nearly two years, with barely any dents. Love that Iron Flask has different covers and lids you can switch to your liking. This brand has my lifelong loyalty because of its dedication to customer satisfaction. I'd only wish there were some more colors and patterns that are 'pretty/quirky', like some other overpriced brands are. This bottle is the best I've ever had, and I've two in different sizes, and put my family on as well.

Outstanding iron flask 40 oz stainless steel water bottle!
This is a must buy water bottle I'd highly recommend it in my opinion I've used it now more than over a year and it has been wonderful put a bunch of ice cubes in it and keeps my water or any liquids in it cold for a good amount of time couple hours or more depending upon how much ice you put in it. I love the black colored marble look. 40 oz is a good size that holds a lot of water used it for playing basketball and other sports and exercise. It got hit by the ball one time and fell over on the concrete and it only minorly scratched it seen in the picture not too bad overall strong durable stainless steel water bottle easy to clean and dry and I love the different head attachments that come with it for whatever meets your preference. I use the twist open top that's my personal favorite one that I always use. I imagine this water bottle will last me years before having to ever purchase another one maybe forever but going from plastic to stainless steel is a must I had enough of plastic ones doesn't keep your water cold is toxic with BPA chemicals and isn't good for your health glad I finally made the switch over to stainless steel and will never go back. Also doesn't leave strange after smells like the plastic water bottles would.

Richtig gute....
Kanne. Halt sehr lange heiß bis warm. Und ist zudem auch noch robust und lässt sich leicht reinigen. Es sind drei verschiedene Verschlüsse bei, der eine ist einfach nur ein Drehverschluss mit einem Ring den man an der Kanne befestigen kann damit der Deckel nicht runterfällt oder verloren geht. Der andere ist so ein breiter fester einklappbarer trink saug halm, sieht ausgeklappt etwas aus wie bei den Schnabeltassen von damals, auf der Unterseite ist ein Kunststoff Strohhalm den man auswechseln kann, was ganz einfach geht, ein Ersatz Halm ist dabei. Eingeklappt ist es auch dicht, es läuft nichts aus, schon paarmal benutzt. Der andere Verschluss ist so ähnlich wie bei diesen Coffee to Go plastik Bechern deckeln. Und auch ein Klappverschluss dabei der dicht hält. Hab ich bisher nur einmal probiert weil mir diese Art des Trinkens nicht gefällt. Alles in allem bin ich sehr zufrieden mit der Kanne und bereue den Kauf nicht.
