Grunwerg Drinkpod Vacuum Insulated Leak Proof Capsule Flask, Stainless Steel, Mirrored Finish, 300ml

ottimo

I use it two years now and it’s excellent! No leaks and it keeps the coffee hot!

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.

Super zufrieden, hält für Stunden warm u. Ist dicht 100%

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.
