    • Good overall experience with product and company
Size: 40 Oz Color: Pearl
Had an all red one for about 2 months before it got stolen, like it enough to get a replacement but it had a minor dent at the bottom. Customer service was helpful in getting that situation resolved quickly and without hassle. All things considered pretty good experience overall with the product and iron flask as a company, would recommend. For the bottle itself, it keeps drinks the same temperature they were put in for quite a while, poured hot water in at night when it was too hot to drink comfortably and then next morning it was a pleasant level of hot. From what I noticed the outer part of the bottle doesnt change temperature due to the drink inside. Lids, they all work though personal preference plays a big part in which you like best. Screw on lid is great for keeping drink temperature the same for longer but isnt great for frequent quick sips. Flip top is good but drinking from the bottle may be difficult for people with larger noses or larger bottle sizes due to the weight and since the hole is so recessed in the lid. Straw lid is convenient with ease of use and cleaning (inner section is removable and comes with a spare), solid top section doesnt feel the best since its rectangular shaped but you get used to it ... show more

    • The bottle is great, but the lids are very basic
Size: 40 Oz Color: Midnight Black
I have been using a couple of Contigo water bottles for the past few years (a 24 oz. and 32 oz. Ashland Autospout), and I really liked them. However, they are not insulated, so will collect condensation on them when filled with ice water. I decided to get the Iron Flask because I know somebody who has one and likes it. I purchased the 40 oz. black bottle. I can fill this bottle with ice and cover the ice in water, and the ice will still be there 8-9 hours later, but only if you're not drinking out of it (I left ice water in it over night just as a test). If you are drinking from it occasionally, the ice is more likely to melt a little faster. Condensation has never formed on the outside of the bottle. The wide mouth is pretty much par-for-the-course for metal bottles; my Contigo tops actually fit well on this bottle. My MSR MiniWorks EX is a little more of a snug fit, but it still fits enough that I feel confident that I could use the two in concert to procure water outdoors. I have also purchased the Iron Flask paracord handle, which makes the bottle easier to carry. I do see some room for improvement, though not with the bottle itself, which has been working out great so far. My complaints are mostly with the straw/spout lid (which is the only one I use), and most of those I only really have because I am comparing it to my Contigo lids. The old Contigo Autospout lids were better in almost every respect; they had a lower profile, they were more watertight, they had a more rigid straw, and you could operate them with one hand. The Iron Flask lid often has to be set on a surface to be opened with one hand. Having a springy spout with a button-operated catch is a much easier and more convenient system to use one-handed. The loop on the spout lid is also just about perpendicular to the long axis of the bottle, which makes carrying it in hand or attaching it to a backpack a little more cumbersome than a design with an more steeply angled loop. As mentioned above, I purchased the paracord handle, and that makes this bottle significantly more convenient. The air inlet on the lid is plugged by a small post that is molded into the drinking spout. This is enough to keep water from pouring out when the spout is closed, but if the bottle is laid on its side, there will be some minor seeping over time. Something like an umbrella valve might make this problem go away. The last problem I have is the straw is not quite as rigidly fixed to the top as I'd like. If you fill up the bottle with ice, it is harder to jam the straw all the way to the bottom because it is held to the lid with a flexible fitting (looks like silicone, maybe). The Contigo straw was less likely to wobble around as you pushed it through the ice, which meant it was easier to put on when the bottle was filled with ice. All in all, I'd say the bottle is very good, but the tops are a little lacking. I would simply use the tops to my old Contigo bottles if they had longer straws that went all the way to the bottom of the bottle, but they don't. Iron Flask should seriously consider creating something similar to the old Autospout lids (or even just licensing the design or something). Even if they sold it separately, I think it would be an excellent addition to a very good bottle. ... show more

    • LOVE IT!

Review Image by Atsila Atsila
One of the best purchases I've ever made. I've used this water bottle every day (literally) for a little over a year and it still looks and works as if it's brand new. The color hasn't faded and it hasn't dented- and I haven't exactly been gentle with it. The lids and plastic straws haven't been compromised even though I run them in the dishwasher to sanitize them. I mostly use the straw lid, but it's nice having the extra lids to use when washing the straw lid. I was worried that lugging around a half gallon by the handle would eventually strip the plastic screw pattern of the lid or break the handle, but they're still going strong. This bottle will probably last a lifetime unless I toss it off a mountain or something. I love the color choices. I'm tempted to buy a few others just for the colors even though I really don't need them. I definitely recommend Iron Flask, especially if you're an outdoorsy type. I fill mine up with ice and water and it will stay cold for many hours even when left in a hot car. These bottles would make great gifts too. Love it! ... show more
