I bought two and put hot coffee in them; the lid broke within the first 3 weeks of use on both, maybe because of the temperature? Bad purchase either way

I got it to try it out since I liked its size and shape.
- The suction cup lids have disadvantages compared to screw-on ones. Sometimes they lift due to air pressure in hot conditions and it seems they could come off easily. And logically, over time, they will loosen.
- Also, the sliding spout is difficult to clean inside its parts, or to remove soap residue.
- Finally, it comes with a metal straw but there is nowhere to store it to close the spout, so you have to constantly be careful not to get it dirty.

it looks fantastic and works better with cold drinks. Hot drinks have popped the lid off, so I don't trust it with hot drinks. and the lid gets stained with coffee which is really hard to clean. that aside, it is nice and works well.

Waterproof and keeps the drink warm for hours. Very practical that it narrows at the base so it fits in the car cup holder.

Very convenient cup mainly for coffee and cold drinks, it maintains the temperature.

Quality. Affordable. Ergonomic. Greek. Worth it! It is no different from other similar products that cost 30€+

It does its job, but the lid is disappointing, it gets dirty and you can't clean it unless you break the plastic closure, which then just becomes pretty much useless

Excellent but the lid doesn't clean that easily. Maybe you should get a second one to have as a spare

I got it as a gift, so I can't say much about this thermos. But it keeps coffee cold for several hours, no problem. It hasn't been tested with hot drinks. I take away one star because it doesn't fit in the car's cup holder. Overall, though, Estia products are VFM. That's why I preferred it as a gift.

Beautiful! It keeps cold and hot even without a lid! Additionally, the lid completely disassembles, is washable, and the trapped liquid is released! Press with the tip of a spoon on the black plastic and the lid will come off, wash it, dry it, and reassemble! Look for videos on the internet/TikTok!

Two stars only, because although impressive, the lid, due to its construction, does not have all the parts washable, so a brush cannot be used, and after some uses, it collects residue and you throw it away. It's a shame because I bought many pieces for engraving.

It is very good and keeps the temperature of coffee, tea, or any other liquid placed inside, whether cold or hot, for a long time!!!

The only reason I don't give it 5 stars is the lid. In the part that slides to close and prevent liquid from spilling, coffee residues remain and are not easily cleaned. This part does not come off for proper cleaning. I would prefer there to be a way for it to be removable. Perhaps a little clip or instead of sliding that part to close the thermos, it could move up and down, which obviously requires a slightly different design for the lid.

Very good quality, no odors, easy to clean, and has very good temperature retention (I use it for hot coffee, I make it at 06:30 and by 09:30 when I finish it, it's just fine).

There are better ones on the market that keep the drink hot for longer, but for its price (it is very affordable) it is okay.

A remarkable glass that does what it should. It keeps the cold...cold and the hot hot for several hours. Since I bought it, I haven't used anything else.

It is amazing...it keeps the warm temperature well and for a long time....Serious sturdy glass....It doesn't lose anything....I would buy it again

I use it daily. I put coffee in at 8 in the morning and the ice cubes are still there at 1 in the afternoon. It has made my life easier and I enjoy coffee just the way I want it every time.

The cap from the spout has loosened after a week of use. Also, it doesn't fit in the car holder, which is why I bought it in this size for the car

In the cold, it's unbelievable. It keeps ice from coffee in the morning at 8 until noon when I make fresh at 1:30 or 2. It doesn't sweat. In the heat, when it's very hot and you have it closed, the lid lifts from the steam, so a little caution there. You don't burn yourself. Overall, super.

Very good for both hot and cold. It doesn't close airtight, but if it falls on the table, etc., it will keep the drink; I never put it loose in a bag, always in hand or in the cup holder in the car. In one car it fits just fine, in the other it doesn't, but I believe it will fit in most. It has taken quite a few tumbles, has some dents at the bottom but hasn't broken, it's worth buying.
Edit: the base diameter is 7cm and not 6.5cm as stated in the description on Skroutz.

Very good for its price.
But it has been very convenient for cold coffee at work, and for transporting it in the car as it fits in the car's cup holder.
In hot temperatures, the lid only lifts slightly due to the temperature.

It does not have a smaller diameter at the bottom than the previous glass from the same company. It may even be a few millimeters larger. So if you have the previous model (350ml) and it does not fit in the car cup holder, do not get it for this reason under any circumstances.

The only positive thing is that it fits in the car cup holder due to its double diameter. But overall, complete disappointment, as its sealing is non-existent. I didn't notice (and I don't think it mentions anywhere) that its closure is not screw-on, but snap-on. So the first day I used it for hot coffee and put it in the side pocket of my backpack, it made a mess. Obviously, if it's not waterproof during simple transport, in case of an accident it doesn't provide any safety, so it's completely useless...
Update 20.04.2024
After several uses, all I have to add is that I wish I could remove the one star I reluctantly gave. The sealing is non-existent. Even if the drink is lukewarm, the lid comes off its place and leaks occur. In addition, the lid will never be cleaned from the coffee residues after 5-6 uses. Overall, stay away!
