It is awesome for preserving frozen beverages. I have had it stay in the car during the summer and after about 8 hours it still had ice cubes inside. With a closed lid.
It can withstand hot beverages for 1-2 hours.

While it maintains the temperature well, sometimes it opens in my bag and the coffee spills. Its lid is not secure. Also, when I drink, a small amount of coffee remains in the spout, causing it to spill when I close the spout.

Flawless. Very satisfying quantity, quality packaging and of course no leaks. However, you need to try a little harder to close the lid properly because otherwise it won't close. It keeps the temperature of the drink at the desired temperature for several hours. It's just a bit bulky to fit in a bag. Of course, I should mention that the packaging does not burn with hot drinks. I recommend it, just sometimes it disappears from the market and it's a bit difficult to find or maybe it takes a while to arrive.

I mainly got it for hot tea and coffee for home, and it keeps them warm or cold for many hours!!! It's not convenient for taking it on the go due to its size and it has a small leakage

Very practical. It keeps hot drinks warm for hours. It is big... it holds a large quantity of coffee. I find it very convenient.

It does not provide 100% waterproofing (for hot beverages, it leaks when filled to 3/4 capacity). It may have a small leakage towards the lip when the lid is closed. This becomes more apparent if you drink even once and then close the lid again. I did not have any issues with cold drinks in general as I also used a straw. I put it in my bag with a plastic bag for safety. The construction quality is acceptable, it's just that the production is not up to the same standards. The first one I bought had worn rubber on the lid, resulting in it not being waterproof at all, and the second one had some small irrelevant scratches on the lid. Overall, it's average but okay for ten euros, considering that it does a good job in maintaining temperature, has nice colors, and is priced normally.

It is the best you can find in a thermos, both for hot and cold drinks. It keeps coffee cold from 7:30 in the morning until five o'clock. It fits a straw in the mouthpiece and is worth every penny, 100%. I bought it again for my family and everyone is completely satisfied

I have had it for only a week, but from the first day I have fallen in love with it! For the purpose I bought it, it is perfect. I bought it just to drink cold water at home and on my walks. It closes well and has no leaks or bad smells. However, the most important thing is that it keeps the water cold for many hours, even without screwing the lid, just by placing it on top. And this is important for me because I drink water very often and I like to drink from the cup and not from the lid. That's why it's not practical to screw and unscrew it constantly. Its thickness is sufficient and gives you the feeling that you are drinking from a regular cup. Even without properly screwing the lid, it keeps the water cool from night until morning.

Perfect! I use it for cold coffee with ice cubes, after 8 hours it's still frozen!! Very good construction for its price.

In washing, it is a bit difficult but because I have a baby, I wash it with the brush that I wash the bottles. It keeps the temperature especially in the frozen. Quite a good product and nice color!

After searching, it is the most economical thermos/cup on the market! (We are not talking about the qualities with 3-4 euros from supermarkets or other big Chinese stores)

It does not leak! Not a single drop!

Keeps the drink VERY hot! (I will tell you about the cold one in a month)

Good lid!

Very nice finish!!

Hand washable, easy

Seems durable

On the negative side, I have to say that it has the worst mouthpiece... You really feel like all the coffee is going to spill, but it doesn't... you definitely feel insecure while drinking :-) if the coffee is too hot, you'll see... you have to quack like a duck and scream from the burning
I can't wait to put frappe inside!

*16-6-21*
Cold coffee with only 4 ice cubes, from 7:30 in the morning, the thermos was forgotten inside the car, parked in the sun until 18:00 in the afternoon and the coffee was still cool

After 1 month of use (with coffee filled to 3/4 of its capacity) and washing exclusively by hand, the lid does not seal reliably, either not closing at all or opening along the way and leaking. I am forced to wrap it with transparent film to limit the damage, while the problem worsens as now coffee spills from the point where the lid joins the lip of the container. I mean, sorry, unacceptable.

I have had it for about 2 weeks. Very good construction, with a non-slip bottom, it keeps the temperature of the coffee quite well for the 6 hours that I need it, and it is very convenient at home. It does not leak, it is very convenient to drink from, and the lid closes and opens easily. The color is wonderful and so far it has not had any issues.
At first, I thought it had leaks because it required a little more force to close the lid, but in the end, it was fine.
For its price, it is simply exceptional.

Perfect for the 9 euros I paid... it keeps my hot coffee warm for at least three hours (I haven't tried for more) it is waterproof, doesn't burn on the outside when I have hot coffee inside, and generally looks very high quality... the silicone base prevents it from slipping and the lid is easy to clean and very practical.

P.S. I give it 3 stars because it has a little rubber piece to seal the coffee outlet... it gets lost very easily

I couldn't imagine HOW good it is! Excellent construction and finish quality, incredible temperature insulation as you don't feel anything no matter how hot or cold the content is, liquid temperature preservation, screw-on lid for sealing, exceptional spout that prevents uncontrolled flow and easy staining, spout cover for hygiene reasons, non-slip base, dishwasher safe. I had bought it for everyday use for my wife and ended up getting one for myself too. A blindfolded purchase, especially at this price.

Very good construction. No leaks in hot or cold, with easy lid and handle. Very honest for its price (10€) and it is the best you can buy! Temperature retention for 12 hours is exaggerated!
