Perfect Flask for Hot Drinks On-the-Go
The media could not be loaded. I purchased this flask for my wife, and it has exceeded expectations! The pink color is stunning, and my wife absolutely loves it. The quality feels premium with its sturdy stainless steel construction. It keeps water hot for approximately 6 hours, which is exactly what I was hoping for when I bought it.The press-to-open button is a fantastic feature as wll you need to do is press and you’re ready to pour. It's super easy to use and seals securely, so there are no leaks to worry about. Definitely value for money considering the practicality and stylish design. Highly recommend it for anyone looking for a reliable flask for hot drinks.

Keeps liquids cool for longer.
Keeps water cold. Not tried hot liquids yet. Bought for keeping water in mainly. Easy drinking spout. They look good too. Would have liked a holding ring for easier carrying.

Great for Fast Coffee on the Go!
The media could not be loaded. Product Specs;Height: 9.1’InchCircumference: 8.1’InchDiameter: 2.6’InchVolume: 425mlEmpty Weight: 290gThe Basics: Not Dishwasher/ Microwave safe.Awarded only 4/5 as the temperature had dropped from boiling to drinkable in 4-5h, so would assume it would be lukewarm at the 12h mark. That being said it still works great for my need.This flask ticks all these boxes! I can run into the staff room, pop the flask open take a swig of coffee and flip the lid shut all with one hand.I brought this to replace my old coffee flask of a similar design. I work on a hospital ward with little to no time for a coffee so I needed something that keeps warm throughout the day and is quick and EASY TO USE. It was also essential for me that the mouth piece is sealed and has little hand contact, to prevent it being accidentally contaminated with germs.THE LOCKABLE top is a fantastic addition, I usually slip the flask in the side pocket of my bag which is then hurled into the boot of my car, while tackling several rounder-bouts on my way in the bag is knocked about in the boot. The lockable top stops any accidental opening and everything being drenched in coffee.ON THE MOVE, if you're looking to use this in a CUP HOLDER the measurements are Height: 9.1’Inch/Circumference: 8.1’Inch & Diameter: 2.6’Inch.The product feels robust and well made, I believe it would be drop resistant from about 1 meter or so (waist/ counter height). The opening mechanism is simple and easy to use. Ideal for someone who might struggle with stiffer more fiddly tops. Outer of the flask remains ambient temperature and is not hot/ cold when held.The coffee tastes great and has no tampered taste from the metal inner that you often find with flasks. Which lives up to the statement of it being "Free of BPA materials, chemical toxins or metallic aftertaste transfer." I have used for both hot and cold drinks. I've pre-made FROZEN smoothies the night before then kept them COLD in the flask and decanted out the next morning (they're too thick to drink from the flask) I haven't tried with protein shake or soup but I theory the same principle would apply that they would be too thick, so simply unscrew and consume or decant if the rim of the flask is too hot.Easy to clean but *DO NOT PUT LID IN DISHWASHER* I've put the bottom flask in once by accident and it was fine, but I wouldn't recommend repeating it. The inside should be ok but the outer coating and build may break down. I simply fill with warm soapy water place cap on and shake lightly, carefully open cap as the pressure caused by shaking may cause a pop. Then let the soap run out the mouth piece and rinse. Wipe the mouth piece dry and store the flask upside down to drain.

Variable quality
We bought two of these, one black and one pink. The black one performs well, keeping a drink warm or even hot for a good few hours. The pink one does not, it is warm to the touch when full of hot fluid so clearly is not insulating well and the drink cools quickly. I always make my husband two flasks at night . It was only after some time I noticed the pink flask was warm to the touch. I mentioned this to him and he then told me the contents are always much cooler. Looking closely at the flasks I can see no reason for this. Is it some intrinsic issue with the pink flasks or is it a faulty flask? If they both were as the black one then it would be five stars.

PERFECT
It keeps my drinks HOT🌡️for an entire school day. when I came home it was still really hot and boiling hot towards the end of school so about 9 hours. It's very well made in terms of material and DESIGN!! 🩵! It has non-slip and lock feature which is amazingly useful because it prevents any accident leaks!! ANDDD 360 leak-proof is true!! it will not worn out if you clean it after each use and care for it ❕❕ I also love it in white 🤍I was also very hesitant to buy it because few reviews are bad! but I'm so happy I didn't listen!! 😍😍

the lid does not close completely
The lid does not close completely and the drink leaks. I could not return it because I did not have time.

Very good Thermos flask
One of the first Flask that actually keep your hot drinks hot for 4-6 hours it only holds enough for a couple of cups but great for travelling.
