Performance 5/5, Durability 3/5

It does its job exceptionally well! It keeps cold drinks ice-cold for hours (especially with ice), hot drinks warm for a long time, and offers 100% leak-proof sealing with no leakage at all, even if you hold it upside down.

The only downside is that its metal dents/creases very easily. We have three such bottles in the family and all of them have dented easily.
In fact, I saw the latest one dented within the first two or three days, without it having been dropped.

If we exclude this sensitivity, it is a very good purchase.

The best thermos I have ever bought and I have wasted a lot of money until now.. And because I read comments about the lid, that it gets cloudy relatively soon.. We wash it with the soft side of the sponge and so far mine is exactly as it was when I bought it‼️ (Iced coffee and 10 hours later the ice cubes are still inside‼️)

Unfortunately, and contrary to other reviews, the drink does not stay hot for more than 2 hours. Also, the interior got stained by the coffee and it doesn't come off. Finally, the material on the lid is quite sensitive, so if washed with the rough side of the sponge it will get scratched, which is an aesthetic problem, but still a problem…

For now, very good. It keeps the coffee warm for a long time. Additionally, not a single drop falls. Very leak-proof cup. For now, excellent.

Excellent thermos, it keeps drinks hot all day and you can carry it in your bag without worrying about your drink spilling. It seals tightly and keeps drinks cold for many hours.

Very good thermos. However, it is not completely leak-proof. If you turn it upside down and shake it, it loses a few drops from the lid.

Before this, I had the one with the 300ml capacity. It had a different rubber on the lid, it almost made a full turn and the rubber would decompress. With the 435ml, maybe I got a defective one or the lid works differently, resulting in leaks. It's a shame because I had rated it very highly, I was very satisfied with the smaller one, unless there are different versions.

It doesn't leak, it keeps the temperature satisfactorily (don't expect miracles, like 3 hours fully cold and other exaggerations). Its quality is excellent, it cleans easily and doesn't retain odors. Overall, a very good purchase that has accompanied me daily at work with my coffee for quite some time.

Excellent. The only downside is, as others have mentioned, the transparent lid easily leaves marks and lines from the sponge.

Nice, but because of its shape, it is not very stable.
It fits a double cappuccino.
Nothing has spilled so far

Amazing product. Exactly as it looks in the pictures, very high quality, holds a large amount of coffee and I can even put it in my bag while full since it closes airtight without any leaks. I highly recommend it, it is the best I have tried for its price.

Okay, it's not exactly what I expected for the price it has. The coffee doesn't flow well when you drink it, because it only has one hole and comes out in little drops, like those baby bottles. Also, it's heavy.

It's good and an incredible beast at keeping things cold (especially the plastic lid), although some dents on the bottom side of the metal body are unavoidable. However, it doesn't keep temperatures for more than 5 hours (especially for hot drinks), so it's just satisfactory in that area, but not worth the €30 I paid for it! Just a good thermos cup, not something to get overly excited about!..

It has a very nice design, it is user-friendly and easy to clean. Its performance, however, is not better than similar ones with a lower (up to half) price.

It is very good and high quality.
It has no leaks at all even if you turn it upside down.
It is a bit expensive but worth the money.
I hope it holds up over time

The product is excellent in terms of waterproofing, and I would give it 5 stars for that alone, but unfortunately, the rest of the review is not as desired. In hot beverages that it has been tested with, it loses its temperature in less than 6 hours. The spout for drinking is quite uncomfortable and makes the whole cup dirty, and the lid is very sensitive to washing. Even with a soft sponge, it gets scratches.

Because I ride a motorcycle, the main criterion for purchasing it was waterproofing. Unfortunately, it has leaks. Small but present. I was completely disappointed considering its price. I would not recommend it.

Perfect, I've had it for a few months and it is everything one could ask for from a thermos. It keeps temperature both cold and hot, and most importantly, it doesn't leak at all! I close it, throw it in my bag, and I don't worry, it has never leaked. I definitely recommend it, it may be more expensive than similar products from other companies and I would prefer if it had a nicer design, but it is definitely worth the money.

Very good for cold drinks, I haven't tried it for hot ones. Excellent quality of materials. Minus one star for the high price and for the base that is not very stable.

The perfect thermos. Ideal size for the car and keeps the temperature (in frozen) for several hours. Many have passed through my hands and comparatively I find it better than others at the same price

The only negative thing is the lid, which as many have said, leaves scratches on the sponge. Unfortunately, I hadn't read something similar before buying it and I have already made some designs on it, but for everyday use it is incredibly convenient, whether it's winter or summer.

From the first time I put tea in it, it stained inside and didn't clean. I wash it exclusively by hand, as I should, yet it has made scratches from the sponge.

It does exactly what everyone says, it maintains the temperature very well, you close it and throw it in your bag, it won't leak a single drop. Turn it upside down, flip it around.
The price is a bit steep, but the rule of giving and taking applies. I bought two, one red 300ml and the immediately larger green 430ml. As someone else mentioned, be careful with the sponge as it leaves scratches on the lid.

Quality construction, I carry it in my bag without any leakage! It maintains temperature (hot and cold) for hours. The only "downside" is that it cannot be washed in the dishwasher and its lid is particularly sensitive... it requires attention to prevent it from getting lines from the sponge. Its cap smells strongly of plastic, but I imagine that it is still new and the smell will go away. It is definitely worth it because you can carry it fearlessly, there is no risk of leakage

It keeps a cold coffee for about 11 hours. All parts are removable (plastic lid and rubber stopper). 100% leakproof so far, even when upside down or on its side. The plastic cap is quite sensitive, be careful not to scrub it with a hard scotch brite as it leaves scratches.

Beautiful and high-quality thermos. It keeps cold drinks for many hours (ice melts after the drink is finished), but it doesn't perform as well with hot drinks, as it only keeps them hot for a few hours. It has 0 leaks, has never leaked, and that's why I chose it, I trust it 100%. It needs to be handled carefully when opening in hot temperatures because it splashes and can stain you. It has been tested and doesn't retain odors, and a simple wash is enough to make it look like new. One negative aspect is that it cannot be put in the dishwasher. Finally, regarding the size of 430ml, it is large, and if you drink normal amounts, the size of 300ml is more convenient.

It holds a sufficient amount of beverage and does not leak at all even if you turn it completely sideways. It maintains the temperature very well for over 5 hours if it is completely closed and for about 3 hours if the mouthpiece is open (e.g. with a straw). It comfortably fits a metal straw and does not retain any odors/tastes from previous drinks after washing. It is definitely more expensive compared to others, but I believe it is worth its money.

Very good thermos cup with good quality construction. It keeps the temperature for a long time and the best part is that it doesn't leak at all, which is why I personally chose it.

Very good, its simple shape makes it convenient to place in the mesh of the backpack or in the car cup holder, the lid closes tightly and coffee does not spill even if it is turned upside down. It is easy to clean and keeps the coffee at a good temperature for a long time (it takes me about 3 hours and something to finish my first morning coffee). Nice materials, the bottom is non-slip and the lid cap is made of silicone, I hope it will maintain its properties for a long time.

Excellent product worth its money and more, keeps warm things warm for several hours and cold things cold. Very good construction and I will definitely buy more from this company, I am very satisfied!!!!
