Lovely Dark & Deep — A water bottle for everyday
Absolutely love this. Bought to replace my bottle I lost in an airport (different brand), I took a chance on this company. It’s fantastic! My water stays cold much longer than my old bottle, no leaking (tested through four flights, three airports, two road trips, & a month of everyday use). Loved the flip lid but also got the spout lids as extra add-ons & they are really great too! Ended up buying four more as gifts for family! Easy to clean, perfect size (larger than previous bottle), & it’s been dropped a few times & no dents or scratches yet! The colour is lovely too!

My 3rd one handy to have more than one
Keeps cold,keeps hot, Don't drop it or it's shot lol seriously these are good quality, buy the silicon bottom and carry case( you can thank me later) 3rd one I bought, beat the crap out of the first one and didn't work as well, I like that you can get replacement top and straw for these

Half Gallon Iron Flask
Exactly what I expected ! Perfect size, actually keeps beverages cold over 24 hours. And I love the color. More than pleased. Ended up ordering a black one for my wife.

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.

I want morel
I love these cups. This is my fourth but not because they needed to be replaced. I just love the colors. I like the 40 oz so I don’t have to refill as often. They keep drinks cold all day. I haven’t tried hot beverages but I am sure that works well too.

The best review ever.
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 water bottle
very sturdy construction, attractive design and multiple lid attachments make this an amazing water bottle for the price. keeps my water relatively chilled for over 24 hours, and keeps it very cold for at least 12 hours after filling depending on whether you open/close the lid often. this is also relatively easy to clean although buying a brush is probably a wise idea. straw and lid detach from one another to make cleaning the straw attachment very easy. 10/10 would buy again
