  • 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

  • Hasn’t Dented, no metal taste, keeps my water cold for long periods.
Size: 32 Oz Color: Pearl
(32 oz) I looked at many different water bottles and reviews of each one to find the best one I could and lots of trial and error with different ones I’ve bought in the past. I work in a factory and was worried about how warm it gets and if my water would stay cold through the entire shift. There are a few days it’s been extremely warm and my ice is pretty sparse in there but it’s still there at the end of the shift as long as I fill it up with an ice tray and water before I go in and keep it filled with water through the day. There’s no metal taste which I’ve found extremely common in a lot of water bottles. Also due to my job I was expecting it to get some small dents eventually and it’s been accidentally banged a few times and not one dent! I also debated on size too and found the 32 oz to work perfectly for me. Due to putting so much ice in it to start my shift I need to fill it up again 1.5 into my shift. I fill it up again at the halfway mark (8 hour shifts) due to drinking it and I’m good until the end of the shift most days. (Some days more depending on heat) I could use a bigger one I’m sure and know now the ice would still last but I wanted to also use it for park days, walking, etc and didn’t want to carry something bigger around. I did purchase a paracord handle to use with it that’s been extremely nice but only works with the wide mouth because of how it needs the lip to attach with in case you are debating what mouth to go with. Also when I say fill up I only mean with water, I am only able to fill it up with ice at the beginning of the day from my home. Hopefully this helps someone with anything they have questions about. Overall, I wish I would have bought this sooner and have spent a lot more money trying others that don’t compare than what I spent on this. ... show more

  • Best water bottle EVER!!!
Size: 40 Oz Color: Cotton Candy
I am so in love with this new bottle, I feel proud to carry it around with me. I have some pretty cool holographic stickers coming in the mail to put on it as well. As most of you will relate to, I tend to create a special “bond” with each of my water bottles, as they carry the elixir of life within them. The quality is incredible, even the box it came in matches the color of the bottle. It did have a bit of a chemical smell on the inside, but that’s totally normal with any new bottle. All you have to do is add a bit of hydrogen peroxide and warm water, shake it up really good, and thoroughly clean the straw with a brush. I do wish it included a brush, but luckily I already had one from an old bottle. To top it all off, it even comes with a lifetime warranty registration! Lastly, I will update this review to let you know how well it keeps my water cold since I just got it yesterday. P.S. I also HIGHLY recommend getting the silicone boot that slides onto the bottom of the bottle! It came in the mail before my new bottle so I tested it on my old bottle, and actually accidentally dropped that bottle with the boot on it. It hardly made a sound AND left no dents! P.P.S. Do not put this bottle in the dishwasher! It does say this in the instructions, but just in case anyone overlooks it, don’t do it! It could damage the beautiful paint coating on the outside. You can put your lids in the dishwasher. ... show more

  • It’s beautiful
Size: 32 Oz Color: Dark Night
I just received my 32 oz “Dark Night” Iron Flask water bottle. This color combo is breathtaking. I’m testing its cold retention now by filling the room-temperature bottle to the rim with ice, noting the start time on my phone calendar. This will be followed by the heat test - boiling water from the kettle. After the heat test, I will update this review. In the meantime, the STRAW LID has a feature that pleasantly surprised me. The handle is HINGED! This is an unexpected convenience - I’ll be able to attach my bottle to my backpack/purse/tote bag. UPDATE: ICE: 42 hrs - first 24 hrs, only 1 teaspoon of melt. At 42 hrs, 1 cup of melt. Bottle was still over half filled with ice. BOILING WATER: 18 hrs - at 18 hrs, water was very warm (gulping temp). I’m very happy with these tests. ... show more
