Cute, but the lid is a bit flimsy--it screws on and off but if it's even a little lopsided, it won't close. If it's not screwed on tight, it affects the insulation, and then if you screw it on too tight it's near impossible to open.

The temperature retention isn't quite as good as other estia products I have (the smaller cup-shaped thermos and a bottle-like design) possibly due to the quality of the plastic lid. But, it's really not all that bad. If I were to buy a tumbler of this type again though I wouldn't go with estia...

(the design is just so pretty though!)

bad material quality, it got stains inside and peeled off outside within a month. I regretted the amount I paid

Very good purchase for work as well as for use at home.
Ergonomic and keeps the interior at the temperature it is intended for

I always keep it on my desk. Personally, it has helped me a lot to drink more water. I wish it came with a metal straw instead of a plastic one, but the tumbler itself is just fine!

I have been using it daily at the office for 6 months. I only put water in it, but it keeps it cool all day and I have increased the amount of water I drink. It has never built up limescale so far, nor does it have any bad odors. I wash it by hand, of course, not in the dishwasher.
I am very pleased!

Excellent. Whatever you put in it stays hot for hours. From hot espresso to ice-cold water. The only drawback is that after 1-2 months it stops being spill-proof.
It comes with an extra straw.

It keeps the water cold, just as it should. For me, who drinks a lot of water, definitely the large size.

Good quality, keeps my water cold if I also use ice, I would really like if there was a cap for the straw, other downside it doesn’t fit in the drink container in the car

Overall, it is satisfactory; I bought it mainly to keep my water cold for hours. Among the 5 insulated cups I have, I would rank it 4th. I would say it keeps the ice for quite a while (about 5-6 hours at an ambient temperature of around 26 degrees), but I definitely expected more. I do not consider it a bad choice, taking into account its low cost as well, but I would certainly not prefer it for more demanding use in higher temperatures. It is a good insulated cup for indoor use.

Very good quality, but it doesn't keep the water cool as long as the classic water bottles from the same company. In the end, personally, the straw didn't work well for me, because it takes effort to suck.

It keeps coffee cold for hours. Anything I’ve put in it, without ice cubes, stays cold for hours. At work, after 10 hours, the ice hasn’t melted.

Very beautiful and practical. The size is quite large. I say this because I expected it to fit in the car's cup holder, and it doesn't fit in mine.

It keeps the water cool for several hours, even without ice. Having used more expensive thermoses, I admit I did not expect such an affordable product to perform so well.
I bought it because I wanted to have a large amount of water available while I work, and it has truly saved me; I drink much more water.

I recently bought the product. The only thing I didn't like is that the straw has a plastic taste.

Great design! Very convenient, large capacity, and it fits in my car's cup holder. Everything is just fine!

Overall, I am quite satisfied, it keeps the temperature in the cold for about 4-5 hours I would say. The truth is I would like the same design in more ml but it does not exist.

It's decent for its price, it keeps my frappe cold for many hours and it's lightweight. I remove 2 stars because it doesn't fit in a cup holder, which is what I mainly wanted, the narrowing at the bottom is quite wide!

It's ok, beautiful as in the photos and it hasn't leaked so far. But unfortunately it doesn't fit in my car's cup holder (Dacia Sandero) while my other thermoses have no problem!

it does not include a brush for cleaning the straw in the package. In my car, it does not fit in the cup holder base

The second one I buy from the same company and it has helped me immensely to drink much more water. This particular one is also very beautiful and truly keeps the water cold for many hours, just like the first one I got.

Perfect, it doesn't leak, it keeps the water cool for many hours! And I finally drink water!

If you want a large glass for home, ok, otherwise it's not worth it. It spills, you can't carry it in a bag, and it also has a plastic straw.

I use this cup allllll the time! It holds about a litre and the prettiness of the cup makes it easy for me to get my water intake in

Nice thing to have in the house for water for example, but the lid doesn't lock on top. Basically, it screws on to lock, but it has a flexible hole for the straw to go in, so if you have something inside and it, for example, tips to the side, it spills immediately and you can't secure it. I don't understand this logic, I wanted to take it with me in a bag but it will 1000% leak.

It has lasted a long time, it is durable! If you turn it on its side or upside down, of course a little water comes out of the straw but that's expected. It maintains the temperature okay, holds a large quantity and is convenient to use. In general, it is heavy and not suitable to carry around for a walk etc. It's meant to be used at home, in the car, at work.

Generally of good quality, but the straw does not draw easily. It takes effort for each sip and this makes it tiring over time

Very good, durable, beautiful. Definitely worth its money. The only negative is that after some time of use, the spill proof wears off a bit. Other than that, it's just fine!

Wonderful and beautiful!!! The color is exactly like the photo and it keeps the water cold for quite a long time!!!!

Decent tumbler however, sometimes when it turns over in my bag it leaks water...
In the summer though, it keeps cold water for over 8 hours.
