The company makes excellent glasses, but this particular one is a major failure. The liquid loses heat quickly, and water and moisture build up between the double walls

It is a cup, so it is only for upright use.
It is not for bags or for tilting, because it will leak a little from the top opening where you drink.
For cold drinks, which is what I use it for, it is very good.
It fits in all the cup holders I have tried: bicycles, cars, and others.

Very good purchase,
it keeps the coffee cold for many hours despite the very high temperatures outside!!!!
In a phrase......it does what it promises!!!!

It always keeps the temperature of the drink! Quite durable, over time it started to lose its color

This is the second one I bought, the first one went into the washing machine (mistake) 2-3 times and faded. It was left inside the car for 6 hours with the sun hitting it at 30 degrees outside and the ice cubes were still preserved. I take it to work every day and after 8 hours they are still preserved. The definition of you get what you pay for

It loses from the lid that closes from the top on the back side. It does not maintain the temperature in the cold terribly and is bulky. If you place it upright, just take it; I, who placed it on its side in a bag, lost.

I have had it for almost 3 years, it's very good, it has been very convenient for me, and I ordered it again. In the cold, it keeps ice for up to 5 hours, I would say. In the hot, the heat doesn't last as long.

We have 3 ecolife thermoses and we use them daily. There is leakage in all 3 with a slight shake or simply by drinking from the spout. At the point of contact between the plastic cap and the metal thermos, it screws on, has a silicone ring but there are losses with what this entails.

After almost two years of almost daily use, it holds the temperature well in cold conditions, but in hot conditions it starts to cool down after two hours. The lid has its little issues, it leaks not from its top but from the point where it attaches to the mouthpiece. Overall, for its price, it is very good.

Update: The lid broke within 2 months.

It is mediocre in everything, from construction to the amount of time it keeps the temperature whether cold or hot.

I will repeat what I wrote about the bigger sibling of the 0.42lt, since I have both. In hot drinks, 4 hours later, they are not hot but at least warm. It doesn't leak within reasonable limits. Even if you turn it upside down, it won't drip, but I don't put it in my bag unprotected because a clumsiness can open the mouthpiece. It is easy to clean compared to other branded ones I had, which had a silicone strip around them that collected coffee inside and you had to remove it to clean it, so it would gradually start to deteriorate or you would leave it as it is somewhat dirty under the silicone. Now it is much easier. I will come back for cold drinks.

It does not keep cold beverages at all and it "absorbed" moisture on the inner wall. Compared to another product from the same company (all stainless steel), it is clearly of lower quality.

As a cup and in terms of size, it is very convenient. However, as a thermos, it does not keep cold beverages cold at all. Ice cubes melt in less than 2.5 hours.

Awesome! The only flaw is that after a few weeks, the external color of the glass fades away.

I have it for 3 months, from the first month the lid does not close well, it has a rubber that if it does not sit straight and does not press well on the cup, it spills everything, and you realize it after half of the coffee has spilled. The lid on the spout, if you don't press it in place to hit the coffee, it also spills and covers the entire top part. Also, the lid of the spout is not convenient for one-handed use, for example when driving, because it hits and closes again when opening it. For 10 euros, it might be okay

The lid broke without any particular use because I always open it to drink coffee, it shouldn't have broken the side part

Very good! It keeps the coffee cold and the ice cubes haven't completely melted after 8 hours. It doesn't have any odor like other thermos. A very good choice, tested only with cold drinks. I have the black one and it doesn't have any issues with the color, etc. I bought it after a lot of searching! Another important thing is that it FITS in small cup holders of various cars!

Very good thermos and perfect for triple freddo espresso. The bottom is a bit difficult to clean, as the narrow spout doesn't allow for hand access

The lid has a rubber seal that provides waterproofing, which in my cup had cracked a bit, resulting in a small leak. Over time and with a little help straightening it before closing the lid, it improved and now it's great!! It keeps the temperature perfectly! I am quite satisfied

All good with the glass. The only thing that bothered me is that the color comes off easily. It comes off with small hits. I would buy it again, but in white or silver color, so that the scratches don't show.

Very good with the only drawback being that the heat of the drink creates condensation inside the plastic. It is purely an aesthetic issue.

In hot temperatures, it leaks, especially if it is two-thirds full. Two hours later, the coffee is just lukewarm. It also slightly alters the taste. The design of the spout is not impressive either. It drips and then runs and makes a mess.

This specific thermos has been tested so far only with cold beverages and it keeps the ice cubes for hours. It is not dishwasher safe, like most thermoses.

I have had it for 3 months. I have used other cups that are supposed to keep the temperature of the beverage and I always throw them away because they do not keep the temperature of the beverage. This specific one is very good for both cold and hot beverages. After 4 hours, the ice cubes still haven't melted and it keeps the coffee in very good condition.

After a year of daily use, I can say that it is the best thing I have bought! It keeps the coffee cold all day without the ice cubes melting. After a year, the wear and tear is really minimal! Even at the beach, they don't melt and you can drink coffee like a human being.. The rating it has is unfair! and it makes me wonder how unreliable reviews are.

I chose this brand trying to make a good and eco-friendly purchase but I was unlucky. The color fades... The foam material on the bottom came off. The lid fell on the carpet (which is also thick) and broke in two places...

The color peels off after a short period of use, while it keeps the temperature of the drinks for a maximum of 2 hours. For example, in a cold drink, the purchased ice cubes completely melt in 2 to 2.5 hours.
On the contrary, a promotional cup from the same company kept the coffee frozen for 6+ hours, even if it was exposed to the sun! However, the color there was also completely unacceptable, it peeled off very quickly!

After a period of use, the color starts to fade starting from the top. On the rest of the surface where the color remains, the texture has changed as it seems that a transparent layer covering the color is deteriorating.

Additionally, it leaks from the very first moment, no matter how well you have closed it. It doesn't leak from the spout, but from the point where it screws in.
