  • Worth The Price-Point; Pros and Cons
Size: 32 Oz Color: Pearl
So this is actually a review including 2 bottles, as I recently bought one to replace the first one I had (first pic/blue-pink bottle) and haven't used the new one (Opal) yet. So functionality review will be based around my experience with my first. For the sake of those looking for a quick answer; I find the product to be worth the price-point. I also believe in getting what you pay for. I had my bottle for around a year (only tossed-out due to my own folly) and it did everything I wanted out of a bottle. Cons: - There was a bit of a weird, chemically smell/taste like others have mentioned. I did get it to go away; cannot say if others could as well. - You run a small-risk of getting a pre-dented bottle? Amazon makes it pretty easy to exchange (for me). -A little difficult to get the gasket in and out, so you can really make sure you don't have any bacteria growth in your lid. - Supposedly "not actually vacuum-insulated". **This is based on responses within other comments. Pros: - Absolutely keeps your drinks cold. Even if you just put the drink in cold, with no additonal ice. - At least sturdy enough to only get a little scuffed-up when it falls to the asphalt from the top of your car and no safety-bands on it. - Good for a long time, as long you don't heck up and let it get gross by accident. And you may even just be more confident in your sanitizing abilities than I am. As I mentioned above; I got my first bottle (blue/pink) about a year ago. I only replaced it because of my own mess-up, where I left Liquid IV I was drinking-on in it for waayy too long (I am ADHD and object permanency/executive dysfunction is a constant struggle) and I was not going to try and believe I could clean it thoroughly enouch, especially since the bacteria had gotten under the gasket as well (the thin, opaque, silicone-ring in your lid that creates the seal. The ring is removable (need something to pry it out), however that's a tight spot and didn't think I could scrub into it enough and feel safe. I don't believe my first bottle came with the additional 2-lids, so that was a nice surprise this-time-around, to have some options. I won't even really touch on the "is it actually vacuum-insulated or not" convo because, as much as I have a vague-knowledge about vacuum-spaces and the science to that.. I have the ability to admit I know nothing about how that applies to water-bottles enough to make some of the statements others have in their reviews. The Company seems adamant in that they are.. and if they have a step within their manufacturing process that involves attempting to create some kind of a vacuum-layer? Then I'm not going to sit here and try to call them liars, just because it doesn't seem to fit an ideal of what that should look like. 🤷🏼♀️ Does it keep your stuff cold?? Yeah, 100%. I have put just refrigerated water, with no ice, and it's stayed cold for hours. Then it's even colder/longer with ice. I did get the weird, chemically smell/taste that others have mentioned. But I just used a straw-cleaning brush to get into the drinking-nozzle and crevices of the lid with some Dawn and really hot water and it was gone. There were a few, good drops that had happened and it barely dented, really even barely scuffed, which was impressive.. until.. lol We come to the original order of the replacement bottle (Opal). Now, I was able to immediately order a replacement (that is 100% fine) and am sending this one back.. however, I am just incredibly curious what in the WORLD happened to it, more than anything?? Lol My old-bottle had never exactly fallen at 50mph onto a curb or anything like that.... But if the bottle in the 2nd pic is any indication to the possible results, I don't recommend being that rough with it. Lol the Amazon bag did not have any damage that correlated to the damage on the box/bottle, so I'm assuming it had already happened before being packaged for shipping to me. With how hard Amazon employees work, I don't really blame them for missing it (or not caring if they did see it lol). If you're looking for a water-bottle that functions and you don't mind the possibility of needing to exchange a faulty one and giving it a GOOD scrub before-use (really should be, anyways)? This is a great choice at a more humble price-point, compared to other brands whose products don't function much, if any better than this one would for you. ... show more

  • Life Changing (Hear me out)
Size: 22 Oz Color: Midnight Black
This bottle is the one I've been looking for for soo long! Heads up, this is going to sound like a shill but its just that good IMO. Multiple lids - Amazing and such a nice convenience. Having the multiple lids have allowed me to use this for 90% of what I drink from now. Materials used - Soda safe! Soda always has a bad flavor from metal thurmice/cups but this one, I can safely say it works. Just be careful with which lid you use for this as carbonation could create a small explosion/leaking. Not a single drop has leaked from this bottle since I got it, 2-3 weeks IIRC This bottle has allowed me to stop buying other bottles and actually drink water much easier (Your results may vary) Ive tried off-brand, cheap, expensive, Yeti tumblers, this one seals the deal for me. Insulation is decent, but dont take my word for that one. I am also not a coffee person, so do your research if you are that type of person. 4/5 stars only because cleaning can be a challenge with the lids. Got extra straw and a sticker with my purchase :) I can't be happier realistically. ... show more

  • Excellent Product and Support
Size: 64 Oz Color: Day & Night
I purchased the 64oz bottle to replace my TAL Hydration version of the same size. I realize it seems a bit excessive to get a 64oz bottle but personally I disagree. I know I'm hydrated if that bottle is empty at the end of the day. The best part is if I put a little ice in there, the water is gonna be cold for a long time. In terms of the Iron Flask version it's really got everything I need. 3 different lids to choose from. I usually use the flip top one which is much easier to clean than the screw cap I was using previously. The black/white gradient design is pretty sick as well. Honestly the best part so far has been the customer service. I tried to order a replacement cap for my TAL bottle and waited....and waited. No response, so eventually I cancelled the order and went with Iron Flask. I didn't realize it came with a lifetime warranty until I received it. Messaged support to register my bottle and it was all done within the hour. I may come back to this review in the future as I've only had the bottle a couple weeks but so far so good. ... show more

  • Great product
Size: 40 Oz Color: Midnight Black
I was in the market for a water bottle that would stay cool or hot throughout the day as my job has me on the road every now and then and hydration is a must. I did not want to pay $60 for a hydro flask as I think that’s just absurd. I found iron flask and even though I’ve only have it for about a week or so it keeps my drinks at a consistent tempature which is ultimately what I was looking for. Also what you get sold me a couple of my buddies said when they purchased a hydro flask they only got the wide mouthed top but with the iron flask you get 3 different tops and an extra straw in case one breaks as well as the item having a lifetime warranty. Last but not least the price point is reasonable and will not break the bank which is always a plus. ... show more
