AORIN Vacuum Insulated Stainless Steel Water Bottle - 350ml/500ml/750ml - 24 hrs Cooling & 12 hrs Keep Warm - BPA Free - Mental Water Bottle for Work, Gym, Travel, Sports

4 stars because the colour isn't true to what you see online and its rather heavy.I've got mint blue in 750ml.It's a good water bottle however, I put cold water in and hours later it's still cold. This is the bottle up against a 500ml bottle, and a litre bottle. I have the 750 and find it too big to bring out with me so I've ordered the 500ml to take to work

Very disappointed having used the bottle twice for water only to find dark staining near the mouth which appears to be rust. Not at all the quality I expected given the cost of the item

Amazing bottle. I have since bought 3 further ones for family members.I have only used it for cold drinks during the summer month so far but it really does keep it cold.I fill it with cold water and add and few ice cubes.I had it in my car on a very hot day for 5 hours, I returned and the drink was still exactly the same cold temperature as I left it.I love the carrier which comes with it too. It stops the bottle getting scratched and makes it easier to hold. It looks good too.My daughter has since got one and it keeps her drink cold all day in school, even though they store the drink bottles in direct sunlight.I originally looked at purchasing a more expensive brand but after reading reviews on here I went for this one and I’m glad that I did.The 500ml one is larger than I imagined on the outer shell but after using it for a while, I could have coped with the 750ml size.

I use mine to keep cold sparking water by my bedside. A big improvement on a pint glass where the water goes warm and flat and can get knocked over.It's basically an insulated steel flask, and I had a few of those from the days when my kids took lunches to school, but this is a bit more elegant and easy to use.It's not just the bottle either. It comes with a neoprene sleeve, a carry strap, and two sizes of bottle brush for cleaning. A nice bit of kit, great value, and I'm sure if I'd bought one at a supermarket with all the cool branding I would have felt slightly ripped off. Not with this one.

Really glad that i purchased this bottle and for such a bargain price!I've seen lots online with the prices starting from £25 and over but don't bother with these ones, this one does the exact same job!I tested it out when i first used it by pouring ice cold water in it at around 11am and it still remained very cold at around 9pm which i was very impressed by as i always thought companies were just exaggerating when they claim it keeps water cold for so long.I don't drink hot drinks so i haven't tested whether it keeps drinks warm for a long period.But i would highly recommend this bottle to anyone!

I was really sceptical about this bottle but have to say I am seriously impressed! It keeps my water ice cold pretty much through a full work day and over night. I haven’t tried it with hot drinks yet but would imagine it being just as good. I am drinking so much more water now and I love the fact that it comes with the little black sleeve and the brush for cleaning. It doesnt leak at all -it’s hands down the best water bottle I have ever owned.

750ml bottle came with all accessories, though it was two days late in arriving (with prime).Works brilliantly to keep drinks cool all day during uni, dont notice much of a weight difference in my bag though I do lug a lot of stuff round.Not actually powder coated steel but more like a plastic sleeve over the steel body. Works effectively anyway

Have used only for cold beverages thus far and it keeps them nicely chilled for a good few hours if you introduce it cold, or with ice cubes (max I have waited is 7 hours). No lingering flavours and easy to clean all parts of the bottle, including the rubber seal (the enclosed cleaning brushes are very handy).Although possible to get ice cubes in, the bottle's neck is fairly narrow so for a conventional ice cube tray the cubes would be too large to fit whole.The neoprene case with carribena feature is helpful for attaching to a rucksack or lunchbox if you need to be hands-free and the case sits securely with no slippage.Slightly too tall to fit into a small rucksack or satchel.Not convinced it is dishwasher-proof as I submerged the bottle on first receiving to clean it and water could be head inside the bottom fixture for a few days following.
