Thoughtfully Designed!
I am a former Stanley refugee, trying to find a new brand since the Quencher wave turned my beloved Stanley into another fashion item, doubling prices and quality guarenteed to sink over time. I was explicitly looking for a bottle with a large capacity, with a wide mouth so that I could easily fill it with ice and clean it easier.I purchased the 1L+ bottle and it's replaced two of my other thermoses as my daily driver. This thing is very sturdy and holds onto temperature very well. More than anything, the packaging and design is really consumer friendly. This comes with 3 different lids, a sports-lid with embedded straw (like the Quencher), a sealed lid with a sliding opening (like a normal hot drinks thermos), and a full screw tight lid with no opening (I presume for maximum insulation). It comes with all these lids, and a replacement straw for the sports lid, which I appreciated a lot. The sports lid also has a caribiner latch, so I can just hang it off a cross-body bag on the way to tennis which I use pretty much every chance I get.The mouth is as wide as they advertise it, making it super easy to fill with ice, liquids, empty, and clean. Given the price, the high quality of the thermos and attachments, and the overall functionality, It's a must buy. So much so that I went back a couple days after and bought another one of these in a smaller version for shorter walks.

Great bottle
I picked up this 1200ml insulated bottle because I wanted something that would keep my water cold during long shifts and days out with the kids, and it’s been brilliant. The size is ideal – big enough that I’m not constantly refilling it, but still easy to carry around.The insulation is genuinely impressive. I fill it with ice in the morning and it’s still cold hours later, even when it’s been rolling around in the car. The stainless-steel build feels solid, and the powder-coated finish gives it a nice grip so it doesn’t slip out of your hand.The lid seals properly with no leaks, and the straw/spout (depending on the model you choose) is really convenient when you’re on the go. Cleaning it is straightforward too – wide opening means you can get a brush in easily.Overall, great value for money. If you want a durable, reliable bottle that keeps drinks cold and holds a proper amount, this one is spot on.

Good bottle, top notch temperature retention
Great product, only used it for a day so far, but my drink stayed cold throughout the day, it didn’t leak, super easy to use and great to help me up my water intake. It’s not the cheapest, but I’m thinking I will get another if this one lasts without problems. Only slight downside is side is it’s not dishwasher safe

Breastfeeding co-sleeping mama approved
I don’t normally write a review but felt compelled to for this. I normally drink out of my Stanley at night when the breastfeeding thirst hits (if you know you know) but ever since attaching a cot on my side of the bed I don’t have a bedside table anymore. The Stanley is very big and clunky for when I’m trying to drink whilst laying down and breastfeeding coz it leaks and it’s very heavy and manouvering the straw into my mouth is really tricky. I also like my water ice cold and I’m always terrified that it’s going to leak onto my baby’s head and make him scream so I needed an alternative that keeps my water cool, big enough to not need constant refilling and leak proof enough so I can be carefree and hydrated and I can just dash it anywhere on my bed and and not worry about it leaking. this bottle has arrived today and solved my problem so thus far I’m thoroughly impressed it’s also quite cute I hope it never lets me down

Good, but scratches easy
Love the bottle overall. Water inside stays cool for hours , even when it’s boiling outside. There are 3 pieces: The bottle, the top and the straw, so cleaning is very easy. It does stretch very easily, and i’ve also got a dent in it , without excessive droppint. It’s also fairly expensive , but worth it compared to a plastic bottle.

Best bottle purchase for cold water
One of the best bottle purchase ever. The insulation is so good. I usually use it for cold water and the water stays cold for more than a day in good weather. And in hot weather, the ice cubes are not fully disolved from morning till evening which keeps the water cold even in 30+ above temperatures. Very good purchase for keeping water cold.I bought 1200 ML in Dark Night color.

Richtig gute....
Kanne.Halt sehr lange heiß bis warm.Und ist zudem auch noch robust und lässt sich leicht reinigen.Es sind drei verschiedene Verschlüsse bei, der eine ist einfach nur ein Drehverschluss mit einem Ring den man an der Kanne befestigen kann damit der Deckel nicht runterfällt oder verloren geht.Der andere ist so ein breiter fester einklappbarer trink saug halm, sieht ausgeklappt etwas aus wie bei den Schnabeltassen von damals, auf der Unterseite ist ein Kunststoff Strohhalm den man auswechseln kann, was ganz einfach geht, ein Ersatz Halm ist dabei.Eingeklappt ist es auch dicht, es läuft nichts aus, schon paarmal benutzt.Der andere Verschluss ist so ähnlich wie bei diesen Coffee to Go plastik Bechern deckeln.Und auch ein Klappverschluss dabei der dicht hält.Hab ich bisher nur einmal probiert weil mir diese Art des Trinkens nicht gefällt.Alles in allem bin ich sehr zufrieden mit der Kanne und bereue den Kauf nicht.

Exactly What I Was Looking For
This Iron Flask 40oz insulated water bottle was exactly what I was looking for. I work in public safety and am not always near the station to refill my water bottle and wanted something that would allow me a couple refills but keep the water cold until I needed it. This does exactly that.I used a 20oz shaker bottle as a water bottle, so this gives Iron Flask bottle gives me two refills until I need to fill it up again. It is the perfect size to keep on my passenger seat without taking up much room at all. I have not had any issues with the bottle leaking and it is very good quality.the bottle came with three different lids. One is just a standard lid that stays attached to the bottle when unscrewed and is stainless steel. There is a straw lid, with a silicone straw that goes into the bottle and a plastic straw on the plastic lid for drinking. The third is a plastic lid like a standard coffee thermal drinking lid. I have only used the stainless steel lid as I only use this to hold extra water to refill my other water bottle since I add a water flavor to it.All three lids have a handle source for easy carrying of the water bottle.I drop this thing all the time and it still holds up really well. Of course it is going to scratch or dent when you drop it, it isn't a magic water bottle. But it has not affected the lids or seals in any way. I like to put stickers on my metal water bottles anyways, so nothing a fun sticker cant cover up!I do not put hot liquids in this water bottle, so I cannot speak to how well it keeps liquids hot, but it keeps my water nice and cold so I wouldn't have any doubt in its ability to keep liquids warm for as long as it says.I would purchase more of this product in the future if I needed.

Great product
For 2 months of heavy use, great product, doesn't change waters taste at all, incredibly sturdy, keeps the liquid cool even after the bottle gets warm from being in the sun (adding ice cubes at the start of the day helps)
