The Iron Flask is an excellent product, especially for the price! Great construction, cute clip on the handle, and most importantly, it keeps the ice in my water clfrozen overnight! I love the color and it's the perfect size. It came with a straw brush and an extra straw. I would absolutely buy this again, but this thing is so solid and well-made, I know it'll be around for a good while.

I’m a longtime fan of Iron °Flask bottles—this 40 oz size is just the latest addition to my personal collection (yes, I rotate through several like they’re outfits). I’ve also bought dozens of these as gifts over the years, and they’re always a hit. Every single one I’ve owned still works perfectly, even the older ones. A few have some scrapes and bumps from being dropped (I’m clumsy—it happens), but they still keep my water ice cold all day and haven’t lost their seal or insulation. I love that it comes with three different lids so I can switch things up depending on whether I’m driving, walking, or just lounging. The quality is super consistent, and they’re easy to clean and carry. If you’re on the fence, just get it. I basically evangelize these to everyone I know and have yet to hear a single complaint.

Im a delivery driver for a major big box store (groceries and the like). This bottle is absolutely amazing. Its large enough to keep me hydrated all day. It keeps my water cool all day even when exposed to high heat and sunlight. It is super durable. It does not leak at all. I love it!!!! I would recommend it to anyone.

Absolutely love this bottle. Very pretty colors. I put a paracord handle on it and it’s absolutely perfect and helps me increase my daily water intake. Keeps water cool for a very long time. So cool, in fact, that I put little to no ice in it or else the water will give me a brain freeze 😅 Nice that it comes with straw lid or screw in cap.

tldr; I've had it for one day, seems pretty good, I support it, if that counts for anything. If you have doubts, take a look at the Aquatix Fliptop mentioned below as it's a great bottle. I'll update this review if anything happens (leaking with a seal in place, container doesn't maintain temperatures, etc.). Update, 3/19/20: I filled my 40oz. Iron Flask with 10 cubes of ice and cold water; the 32 oz. Aquatix with 6 cubes and cold water. I figured the 8 oz difference warranted more ice for the Iron Flask. It's been 3 hours, and the Iron Flask's ice is all melted, but the Aquatix is still going super strong, all six cubes are there, albeit 1/2 - 3/4 the original size. If you're looking for something to keep your drinks cold, the Aquatix is the way to go. But I'm sure both bottles have their merits to each individual person. To begin, I use an "Aquatix Fliptop double insulated vacuum sealed 32 oz." So why'd I buy this? I live in a pretentious town that thinks its amazing, but the drinking water served everywhere is pretty terrible without a filter. That's just America these days, and if you disagree, just give it time to reach you, or maybe you're already acclimated to terrible water and can't differentiate anymore. I go to the gym, smoke a few j's with friends and hike, I walk 4+ mi's and run 3+ mi's every day, not including sprints. I partake in archery, rock-climbing, and bowling; I'm active AF. So, I thought, if I'm gonna want decent drinking water throughout the day, then I'll need another bottle. I also thought that instead of spending $100 on White Russians during my bowling leagues, I could just buy the $30 supplies, mix it, and keep it in this BLUE 40 oz thermos. I think 16 oz. would suffice, but better safe than sorry. I checked google for the best drinking bottles; then correlated it with Amazons selection. Thus, here we are with Iron Flask. SO first things first: TEST FOR LEAKS. I'm only going to be using the straw lid, so I tested it out-- there's many notorious reviews commenting on it. I didn't experience any leaks with that lid. I'm assuming the leaks are probably because these people lost the rubber seal that goes inside the lid, along the rim; or maybe the flip top isn't closed completely. Secondly, it's pretty easy to handwash. I just put a little soap in, hot water, and shake it for a few minutes like I'm mixing a cocktail. Could it be easier? Yeah, it'd be nice to throw this into the dishwasher. We can build spaceships, sell $200 phones for $1600, quarantine an entire country because the healthcare system is a joke-- so I dream one day we can make these bottles dishwasher safe. Lastly, the styling is amazing. I got the 40 oz "Dark Night" variant, but if this holds out for a few months (if not years), then I can absolutely see grabbing the "Dark Rainbow," and "Lime," variants too. They all seem to look nice though. So what's wrong? They give you an extra straw, three lids, BUT NO REPLACEMENT SEALS. My Aquatix came with a replacement seal, which I actually needed as I noticed it was leaking, and found the seal to be gone. Busted out the replacement and its been going strong for almost a year since. You don't know what you got 'til it's gone, and I promise, a replacement seal is very welcome. Hopefully this review helped, it's a great container. If you have any doubts, I can swear by the AQUATIX I previously mentioned: it's been solid, dropped dozens of times, still going strong. The best part is that I can put 4-8 ice cubes in it, cold water, and go throughout the day, 6-8 hours, and have it be as chilled as it was when I filled it. I've filled it with ice and water before bed, and woken up to the same ice cubes floating around. I capitalized AQUATIX so you know this last paragraph is in regards to the AQUATIX.

Love this bottle. Keeps ice pretty much all day and not much melting at all. Holds plenty of fluid and the straw drinking option is fantastic to use. The carabiner hanger is nice, and I also added a paracord hanging accessory to it, so it gives me options for carry or keeping in my vehicle when driving. I use this every day and works great and is very high quality. I looked at other brands and never had an Iron Flask brand but will certainly buy this brand again.

I love my Ironflask. It keeps my water cool for more than a day. It is strong and stylish. The lid has never leaked on me even though I'm always knocking it over. Having it nearby keeps reminding me to drink more water. I added the rubber bottom and may get the braided strap as well. My only wish was a way to keep it upright and beside me in the car. (It will not fit in cupholder. I suppose that's a problem with all these big drink flasks.) The stainless steel inside is always clean with no plastic tastes impacting my drinks.
