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.

Cold forever!
Okay so this thing is an absolute game changer. I bought one for my wife last year and she loves it. I'm a dummy who doesn't drink enough water and gets wicked kidney stones, so she recommended I get one too. This flask has finally started me in the right direction of drinking enough liquids in the day. It stays so cold for so long, I usually only have to add ice 24+hours later, even after a refill or two. I pee so much, it's annoying to pee this much , but apparently this is how often normal people pee.

great product
This is an amazing cooler or flask or water bottle, whatever you want to call it. It keeps your drinks cold for at least 24 hours. My wife left it in the golf cart at the course. I picked it up the next day and the ice was still solid it did not melt. Now you could buy a couple of other water bottles from some of the name brands and pay at least twice what you are paying here, but you would not be gaining anything. The only difference is that you cant put a design on this. However the colors are pretty cool. I think i would rather save a few bucks and live without the design. I love this water bottle/ flask/ or cooler. I would highly recommend this item.

Solid, Great Color!
BEAUTIFUL color. Solid construction material. No leaks. Keeps water cooooooold all day. Love the different lids available. Replaced my decades old hydroflask bottle that cracked internally. This baby is a fraction of the price for very similar quality. 10/10

Love it!!
This bottle is great. I was afraid it would be too big for me to hold comfortably but it's not at all. The color is beautiful and the bottle feels sturdy. I've filled it with ice water, and it still had plenty of ice in it more than 24hrs later. I drink wayyy more water since I got this bottle and I carry it with me everywhere. There's some weight to it when it's full, but not too much. I HIGHLY suggest buying a paracord handle to go with it. I couldn't imagine carrying it by the handle on the lid. It's just not effective. This bottle has the lip required to use the handle and is very secure. I thought the bottle came with a straw lid, but it doesn't. That's the only thing I'd say is missing. Also, as shown in my second picture, when it's full of ice water, condensation forms on the lid. I don't care, but someone might. However long this bottle lasts, I'll buy this one again when I need to. It's more than met expectations, even at what I would consider a lot of money for a water bottle. It doesn't leak when used correctly. I've had 2 leaks, both bc the nylon cord from the paracord handle that goes around the lip of the bottle, had gotten under the lid when I screwed it on. I rectified that by putting that cord under the plastic ring before putting the paracord handle on the bottle. It was HARD to put on that way, but I havnt had an issue since.

Very good alternative to more expensive water bottles
I got the 40 ounce version and it does the job. It stays cool and hot as advertised. The color was striking and accurate to the purchase page. I absolutely love the three tops that come with this bottle! They are all leak-"proof" and give you the option to drink how you like with the exception of a straw. Sometimes hotter drinks leak with the sip top when shaken but this seems minimal. Beware that this size will not fit in your normal car-size cup holder. That said, if your car can accommodate it, you can buy a cup holder expander to make this larger bottle fit just fine. I did this as my kid likes the larger water bottle for work.

Half price Hydro Flask
Seriously, I don't know why anyone would buy a Hydro Flask at $60 when this product exists for around $30. (I also bought the rubber boot for about $10). I've used this water bottle 2-3 times a week for the past 6 months. I've cleaned it in the dishwasher many times (even though the bottom of the bottle says not to), and it basically looks brand new. It comes with 3 different lids, although I only ever use the spout lid. One of the biggest selling points for me when choosing this water bottle was the fact it does not need an internal straw. Straws are a pain in the butt to clean properly, and go missing all the time. The spout lid works just fine without one. It's well insulated (there is some condensations around the plastic lid area, but that's all). And, its never leaked. What more can you ask? Great product. Highly recommend.

The most amazing brand of insulated bottles and tumblers there is!
I love Iron Flask so much. This is my third purchase. I really wanted morning mist. I kept waiting and waiting. That color was finally back in stock and I received it yesterday. Wow, I'm using it today for my iced coffee without ice. I can not believe how cold it keeps my coffee! I thought my old tumbler was so great. It was not. Nice ergonomic design. Easy to grab and hold. Very functional. Well made. Keeps drinks cold for days. No smell. Size is 40oz. It's the perfect capacity for me!

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.

Overall Great Bottle - missing lid sealing
Hight Quality Bottle, which is worth each penny. Just one Issue I faced. One of the three lids had no sealing ring, which causes the bottle to leak. I can't imagine how this happened, but it's a little disapointing (Explains the missing 5th star). Size is perfect and the lids feel very solid eventhough two of them are made from plastic.

Gute Qualität und Thermoleistung
Die Qualität wirkt gut und auch optisch sieht die Flasche gut aus. Durch die verschiedenen Aufsätze ist für jede Situation das richtige dabei. Auch die Thermofunktion funktioniert gut. Mein gekühltes Wasser bleibt den ganzen Tag kühl. Einzig die Flasche geht leider nicht in den Geschirrspüler.

Icy cold perfection!
I’m amazed by the quality of this product at such a low price. I filled it with ice then topped it up with water expecting that I would then have nice cold drink for the next few hours (which I did) but I actually expected the ice to eventually melt and what amazed me was that 20 hours later there were still ice cubes left in it - along with the ice cold water!

Tolle Flasche
Obwohl die falschen Aufsätze dabei waren, liebe ich die Flasche. Würde ich immer wieder kaufen
