Great idea to have a gap in the lid and for the coffee to spill at the slightest movement even though it's supposedly "sealed." If you want a thermos that doesn't leak... get a different one

Beast, I put water from the fridge in it in the morning, go to the beach, come back at night, and it still has the same temperature as when I put it in.

EDIT: After a year it still works perfectly. It has taken a few falls but they don't seem to have affected it. I recommend it.

Vfm is very good thermos, it has been tested with cold water and it keeps it all day, also it is of good quality construction.

Flawless! Frozen water at work for the entire eight hours. And lightweight and waterproof closure. It doesn't retain odors and cleans easily.

After two months it's useless. It doesn't keep coffee hot for even half an hour. When I fill it, it immediately heats up on the outside. At first, it was okay. Money wasted

The only thing that is certain is that if it is closed properly, it does not leak at all and it keeps the temperature of hot drinks even when it is cold outside!!!! Excellent product after 2 years of use, it is still reliable!!! However, even in storage, it must be washed correctly with a brush and the lid as well, as stated in the instructions. Highly recommended!!
NEW REVIEW: In the 3rd year, it does not keep drinks warm for even three hours with an external temperature of 20 degrees. For the price it has now, it is not worth it. For the 12 euros that I bought it, it might be worth it because it obviously has an expiration date.

Well.... after two years of use, the plastic under the red safety broke and so the thermos doesn't close, the IMPORTANT problem is that you don't have the ability to find it as a spare part so the thermos is now useless.

A wonderful product.
Very good material quality.
Very convenient.
Impressively maintains the temperature of the stored liquid.

It keeps hot-cold drinks at the right temperature all day long. This is very positive. It closes very well, there is no chance of leaks. The negative is that it is quite heavy. And it is not easy to clean.

I have bought dozens of products of this kind. It is the most durable and high-quality one I have ever bought. If it lasts for more than 2 years of daily use, then it will be worth its money.
After one year of daily use, it continues to be in excellent condition.

I come back after a year and a half of daily use and confirm all the above. It is still like new.

Very good choice!! It keeps the water for my princess's milk warm for 10 hours!!!! Sturdy construction and practical!!!

Excellent product! We got it to keep our baby's milk warm and it does it more than enough!

There isn't. I filled it with ice-cold water in the morning, went to the beach, and when I came back home in the evening, I took the last sip and it was still cool after so many hours. Also, the lid serves as a cup. It seals well and there is no chance of leakage, not even with balls. I know it's expensive for a thermos, but it's worth it.
