I bought one about two years ago and recently bought a second one on sale for 12 euros.
It keeps the drink cold for a long time, I would say it has good performance.
However, after some time, the color on the outside of the cup started peeling off and a few times some small pieces almost fell into the drink.
The biggest problem is that I noticed the first one I bought recently has leaks, but the new one I bought seems to seal well and doesn't have any leaks.
So, depending on the usage, it will last satisfactorily (external wear and tear and waterproofing) for one or two years.

I have 4, 2 of 370ml and 2 of 420ml. They proved to be indestructible until an unrelated employee at a coffee shop broke the latch on one of the lids. Of course, I bought the same one again. They keep hot and cold coffees wonderfully. They don't leak if you make sure to close them tightly. The difficulty in cleaning concerns the height of the 420ml ones, so I use a spoon to turn the sponge inside to wash it from the milk foam. One tip, for freddo coffee, use silicone or reusable plastic ice cubes to keep the coffee cold without diluting it.

It is exactly what you need. It keeps the temperature very well, even if you put ice-cold water inside, you won't feel any cold on the outer surface. It is easy to clean due to its shape and fits comfortably in the car holder. The only problem is that it is all metallic, so if it falls after a while, the base will not be completely flat. However, even though it has fallen many times, it is still fully functional without any problems

I have been searching for a long time for a thermos cup that fits in a car cup holder. The product meets all the above requirements, comfortably fits a 4-pack of Fredo and keeps ice for at least 6 hours.

I have had this specific glass for 4 years. I only use it in the summer inside the house for iced coffee. It keeps the coffee cold for several hours. At least 4 to 5 hours (maybe even more) as long as there are enough ice cubes inside. For example, I put in 8 ice cubes. During the summers, I literally use it every day. I have never tried it with hot drinks. The only negative thing is that from the first week, the bottom started peeling off and the metal became visible. Also, it came with a damaged bottom from the company and it doesn't sit completely stable on the table, but it's okay. After so many years of use, the bottom has completely peeled off.

The first year is fine, but after that it doesn't maintain the temperature or seal as it used to. You pay 20 euros for one summer, for me it's not worth it.

I have it since the summer of '18. I still use it on a daily basis and I am very satisfied. It keeps the temperatures of both hot and cold drinks exceptionally well, especially at the beach. Even when it was still black, after three hours it still had ice inside. It keeps the contents cold for up to 8 hours at work. The color started fading after a few months, which was expected. I completely repainted it with a little acetone and now it's silver. I haven't had any issues with the lid, and as for leaks, I never put the thermos inside my bag, always in the side pocket, so I have peace of mind. Overall, if it falls, the contents spill slowly, so there isn't much damage if you notice it quickly.

Well, so far it's been great... 20€ seems like a lot though. It maintains temperature, the ice cubes melt in half an hour (I don't know, some say it keeps them for hours and it's not true), but the temperature holds for hours... I don't like it very much because the water has a strange metallic taste, but it doesn't bother some people... the capacity is great

I got it in black. Very beautiful at first sight and generous in its capacity as well as in its quality construction. The first - and very basic - problem is that the screw-on lid does not seal even though it has a flange. And it doesn't seal no matter how tight you screw it, resulting in leaks if the glass turns on its side. The second problem is that after about 10 washes, the black exterior coating peels off and comes off, causing the image of the vessel to deteriorate. If someone is a little careless, they may even drink a small piece of the paint if it happens to fall into the glass...
Overall, it is a good product but expensive for what it offers.

I was hesitant because it costs 18€, but it is ultimately an amazing cup!!! On hot summer days, you put cold water in the morning and it stays cool until the evening. You put an espresso shot in at 9:00 in the morning and the ice cubes melt by the evening. Additionally, you are being environmentally friendly as you are not using a plastic cup. The only "issue" you might encounter is that because it is big, it may not fit in the car cup holder. Nevertheless, I highly recommend it.

Excellent, I stopped using any plastic, from cups to straws, and I wouldn't change it for anything, as it keeps my coffee (which I drink slowly!) cold for at least 2 hours! I bought more pieces too!

I have it for almost a year and a half. In terms of construction, I don't even discuss it, it is one of the best on the market. Now, as for usability, personally I only use it for cold drinks and it does its job just fine. Of course, don't expect it to keep ice cubes after a few hours like those old-fashioned large bottles with foam insulation, it doesn't play with that at all, but overall it is very practical. The 4 stars are for its only negative aspect, which is the color that unfortunately starts peeling off after a few months.

Without having read any corresponding comment, I bought this thermos and from the very first week it has leaks. (The truth is that they are drops, but after a long time there is a problem)

Apart from being eco-friendly, it is beautiful, convenient, and keeps the drink cool for a long time. I will also try it with hot drinks, but for now, I have no opinion on it. Also, the thermos cup was at a very good price!

Very good quality construction. I mainly use it for iced coffees and it keeps the ice cubes intact even after hours. Compared to a NAVA that I have, it is slightly better, as the ice cubes do not last as long in the NAVA. The only negative is that the color fades on surfaces that are rubbed more, such as the base.

Compared to the Nava glass, which is almost similar in design, this one seems one level above. It has thicker walls, which means that it is truly double-walled, with an air gap to maintain the temperature of the beverage. The color shows vulnerability, as it was already peeling in some places when I bought it, which is why the store gave me a 10% discount from the original price. It is definitely the most high-quality glass on the market, as I also have the Nava, which is also commendable, and I have a good basis for comparison. Because I use it for coffee and water at work, I don't mind spending 5-6 euros more compared to the other cheaper ones available here. So, if someone wants it for work, without hesitation, go for the top choice for a small price difference.

All good. The only significant drawback is its diameter, which does not allow it to fit in a car cup holder.

Update: a) What I mentioned about the cup holders only applies to the small ones in diameter. In the previous one, it didn't fit, but in the new one, it fits just fine.

b) Over time, the external paint slowly fades, but at a very slow rate, which I consider normal.

Very good, especially for use outside the house. The only negative thing is that it peels off the color on the corners (I have had it for 2-3 months).

Very good and sturdy.. It doesn't break anything, I just personally find the straw too thick to drink coffee.

Bigger than I imagined, the color of the product is as golden as it appears in the photos! It is a dark copper color! The quality looks exceptional!
