Excellent Value and Leak Proof!
Fantastic water bottle. I got this for work, because I wanted something that would keep my water cold and safe from any contamination. I work in a very dusty and dirty factory, so having something to keep my water clean is an absolute necessity. I used to just re-use a 32oz Aquafina bottle for my H2O needs. That worked fine, until the summer months and my water would be warm and nearly undrinkable within 15 minutes of filling it. This bottle keeps my water icy cold and lasts all day. I put ice water in it at the beginning of the day and 10 hours later, it's still icy cold and there's still ice left! It comes with 3 different tops to fit your needs. One has a straw, one is like a traditional coffee style thermos and the other is just a plug style top. I prefer the straw type one myself. It is also water tight, no matter the top you use, so you don't have to worry about it leaking. I am very impressed with this water bottle and would definitely recommend it to my friends and coworkers. You cannot beat this thing for the price. Absolutely a must have!

Best water bottle ever!
This is my second purchase from this company. My first purchase was 3 years ago, and that bottle (which is the 32oz version of this product) is still working like a champ. I did manage to wear out the flip lid, and it no longer managed to seal quite right... AFTER 3 YEARS of basically constant use. I drink at least a gallon of water a day, and I am not nice to water bottles, as I farm and raise chickens. This bottle has withstood hours on a tractor, a mower, the floorboard of my car... etc... think basically everyday 4 wheeling, for 3 years. The double walls do work wonders. I've left my bottle in the car, in 105⁰ heat, and the water was still cool when I came back an hour later. The powder coating has also held up. I haven't managed to break anything other than the lid in 3 years. I highly recommend this bottle. The new bottle has a straw lid, which I figured I'd try, and it is easy to clean. Definitely buy this bottle.

Best flask ever!
The absolute best flask I have ever used. Keeps water cold for quite a while, and even longer when ice is added. Love the color design and the different tops to use for it.

Fits securely in my car cupholder without tipping.
I love the fact that this fits in my car cup holder nicely. No tipping over! I like that the color was true to what I was expecting, a nice lilac color. Keeps my water cool/cold for as long as I need it to and have not had issues with leaks or drips. The paint is chipping some on the metal part, but I'm really rough with it. It is not chipping in a place I'd worry about accidentally ingesting anything bad. The top is plastic and secures nicely.

Great water bottle
I got this for my husband and he loves it. The size is great and he only has to refill it once during the day at work. It stays cold with the ice for a long time and does not leak.

Love this flask!
Fantastic water bottle for car! Love the straw design although the first few times of use tilted the bottle to get a drink. Exterior may feel warm but the water inside is still cool after being in the car for a few hours. The color is beautiful and like the thinner design that fits in several of my bags. Thinking of buying a second one for my desk. Leakproof so if the cat knocks it over no harm is done.

Nice bottle. They really missed an opportunity with the logo though.
I got the dark purple option of this bottle and it is super pretty and very handy. All the lids are leak proof and seem to be holding up well. I haven't put it in the dishwasher but it's easy enough to wash by hand. Keeps my drinks cold all day. Overall it was a good buy. My issue is with the company logo. The company (or bottle or whatever) is called "Iron Flask", and the little logo thing is an "F" in a square with a little degree dot up in the corner. Like fahrenheit inside a square. Like its cool if you want your logo to be something referring to temperature because this thing keeps your drink cold, I guesssssss it makes sense, but with some tweaking they could've made their logo way better. It could be an "Fe" with a square around it. So simple. So similar. Why would they do that, you ask? Because they're called iron flask, and "Fe" is the symbol for iron on the periodic table. This missed opportunity almost ruined the whole bottle for me because I literally can't even look at it without wondering why they wouldn't make that change. If they had a totally different logo, I wouldn't even give it a second thought, but it already looks soooooo similar to the periodic table symbol for iron, it's like they did it on purpose. Like there was some kind of meeting where all the little execs got together to figure out a logo, and someone said "listen guys, we can have a cool periodic table logo playing off the fact that our company is called iron flask. heres my sketch for the logo design, its just a square with Fe in the middle." and some dude named Chad was all like "Okay Bob you freaking nerd, no one knows what the periodic table is anyway. So let's take your idea and tweak it so it makes absolutely no sense. Who's with me?!" and everyone was with him, because Chad is cool and reminiscent of the high school jock they all wanted to be friends with, and Bob has unresolved high school trauma that was triggered by Chad calling him nerdy, so he won't stand up for himself and his awesome idea. And now we all have to suffer for it. I'm sorry for pointing this out to everyone reading my review. But if I can't unsee this missed opportunity, neither can anyone else. My hope is that with enough people taking the same issue with the logo, this company will finally cave and go with Bobs idea and tell Chad to shove it. I'd like a replacement bottle as soon as they do because it's inconvenient to not get the outside of my bottle wet so I don't ruin the sticker covering up the faulty logo.

Looks good, nice slim size, fairly lightweight, seems leakproof so far. Nice to have different straw, spout options.
