ContigoDrinking Bottle Autoseal Chill Matte Black, stainless steel water bottle with Autoseal technology, insulated bottle keeps beverages cool for up to 28 hours, BPA-free, 720 ml

I have two of these bottles and I would highly recommend them. They are durable. They keep your water cold for up to 8 hours. I have had this bottle for 2 years now and it's still as good as it was when I first bought it. Highly recommend it. It's easy to clean. The size is good as it holds the amount of water I need. The design is excellent and it does the job that it should do so. It functions really well. I keep it in my car every time I go out so it travels with me.

This was a second purchase for my partner. Used daily, the drinks are kept cold. Press button is easy to dispense liquid and there's no straw, which for me was a plus.Well designed. If taking on a plane, the lid can expel the pressure but I always press the button to avoid liquid splurting.Easy to clean, especially if you have a long silicone bottle cleaner. Bottles stand up to the test of time with minimal paint peel. I've dropped it a few times and it's proved to be robust! This bottle pays for itself quickly and it's good value for money.

Great bottle. Keeps drinks nice and cool for hours. Doesn't leak, good water flow from the spout, and fits into my sidepockets of my backpack nicely. Feels sturdy and weighty.However, not sure how hygienic it is to have some working parts exposed. Could be hard to clean. Time will tell and I'll let you know. Also, I'm interested to see how robust it is as I am a clumsy so-and-so and it looks like it could dent easily.For now, 4 stars.

Does what it says, keeps cold, flat drinks really cold for ages! Took this to hospital for the induction of my second baby and it was a god send to stop my water getting to room temperature and was easy to use one handed when my little one arrived and I always had one hand busy.Cleans easily too.

This is by far the best water bottle I've had and I have tried many. The seal is brilliant. Never leaks. The opening isn't too big so you get a nice mouthful when drinking. I tried out how long it will keep water cold for and it just starts to warm up after 40 hours. I haven't tried hot water as I only use this bottle for cold water however if any of my other Contigo bottles are to go by then I know it will be very good. Cannot fault Contigo at all

My recommendation is to save your money for the following reasons.The description about 28 hours is a pure genuine lie to make customers buy the seller’s faulty products.I bought this flask in May 2024. Inside the house, it used to keep the water cold for about only from bed time about 11 pm till morning.When I started to take my dog out for a walk or for his new agility training that started at the end of July 2024, the flask did not last for two hours. The following Saturday, I filled half of it with cubes of ice, It only lasted for about 2 hours. Last Saturday, the trainer sent me back with my dog as the water is too warm for him in that weather.Today, I called Amazon to report the issue and explained everything above suggesting that it might be due to the seal or the quality which is proven under outdoor test. After explaining all the above, Amazon said “we can’t help you with this as return window is closed. Is there anything else we can help you with something else.”We buy these sort of flasks to last for couple of years not for one month and to keep water cold during the Summer. So, there is no difference at all between this flask and any cheap plastic water bottle. So, it’s basically money down the drain.Zero star.I am still waiting for the seller to deal with this issue in a proper satisfactory manner.I will update my review accordingly about the seller’s situation to this utterly frustrating issue.

Does exactly what it says. Seals and keeps cold.No issues with the lid. To let it go mouldy is down to the user.Keep it clean and wash regularly you'll be fine

This is the first bottle I’ve bought that generally doesn’t leak at all! It’s a little bit fiddly to get the lid on perfectly as it needs to be on perfect to stop leaks but other than that it’s great!
