Drink Pod Vacuum Insulated Leak Proof Capsule Flask, Stainless Steel, Satin, 300ml

It's a really nice flask. After boiling the kettle, I brew my tea for the flask, and at the same time I prefill the flask with boiling water and close the lid to help it retain the heat inside. After about 3 mins, my tea is ready and I then unscrew the lid and pour out the boiling water inside, and then pour the tea in. Can get messy if not using a funnel. I always do this over the kitchen sink. Never skip the prefill with boiling water. I tried not prefilling, and my tea was pretty lukewarm and on the cold side when I drank it 2 hours later. It was that rubbish without prefilling. Also I always wash this by hand so it is in good condition. I would personally not place this flask's components in the dishwasher as the 2 O-rings may get deformed. It may seem a bit costly but has already paid for itself after a few trips out. Used to spend a small fortune on teas when I am out. How lovely it is now to always have a nice hot drink in my bag when I'm out and about. It also has a great seal. It has never leaked even though I usually place it in my rucksack and does get jostled about a fair bit, to the point where it is never in a standing position when I open my rucksack to search for it. Yet it still never leaked. This is exactly what I was looking for.

Unfortunately due to Covid-19, this flask is currently out of action. However the times I have used it, it was great. Kept a (standard) mug of coffee at a good drinking temperature about 5 hours after I had made it. Haven't had any issues with it leaking, I commute so this is a biggie for me. To be fair, it is kept upright in a satchel style backpack and its held in place by all the other things in the bag but I did test if it leaks by turning it upside down (it didn't). Really compact and slim as well.

It keeps my hot drink very hot for a very long time I one time 6 hours and piping hot! Perfect size I love my flask great for uni!

Reviewing the 300 ml version: Size & shape: The flask larger than you'd expect for something that holds a mug-sized amount of liquid. Its tall shape and slightly un-level base makes it really wobbly; especially when empty. As it's slimmer than a typical water bottle it's a loose fit in backpack water bottle pocket. Leak-proof? Around the neck of the flask is a plastic seal which doesn't fit properly and falls out as soon as you pour its contents. Oddly it still appears to be water-tight when closed with this removed. The screw thread seems a little iffy though and I've noticed the lid can pop-off sometimes. Insulating: Seems to keep things warm fine. 1 month later: I'm looking for something else as I no longer trust the lid to stay on.

Bought for my wife so that she can carry it in her bag to work. Perfect size and keeps drink warm for more than 2 hours.

This flask is FANTASTIC. It does state that it is for drinks, but I needed something to take soup in that would keep it hot. After trying 7 different tyoes of flask, all promising to keep soup/drinks hot for at least 8 hours, and all of them faling miserably, I finally hit the jackpot with this one.I only need it to stay hot for 4 hours at the most. This little flask keeps my soup piping hot! I will be purchasing another one in the future.

Boiling water will stay hot for at least 6-8hours. A drink which is 75% boiling water and 25% cold water will stay at a hot temperature for 4-6hours. I have not tried with cold products yet. Buy it, you wont regret it.

These are great little flasks, but they don't have a cup built into the lid. A little more thought in design and there could have been a cup in the lid. Not suitable for little children as the content rush out when tipped up to quickly.
