The cup looks nice and is fine to use when sitting still, but it’s overpriced for what it is. Every time I walk with it, liquid leaks from the top, which makes it frustrating to carry around. Two of my friends have the same cup and they’ve had the exact same problem.

Very expensive for a product that initially seems very high quality. First of all, from the very first day, one of the two we got did not seal well. After a few days, the second one also started having problems. The pink one, in fact, has a design flaw where the wheel inside, instead of being yellow like the orange one, is black, so you don't know when it's closed or open. Finally, there is a color mismatch between the lid and the body, which was at least annoying to me.

Defective. Terrible for 45 euros. I threw it away today.

The ice cubes stay in the glass for about 12 hours. I am impressed. Care should be taken when using hot beverages.

Positives:
- very nice design
- maintains satisfactory temperature (especially for cold beverages)
- good build quality
- durable against drops (I've had it for 2 months, it has fallen a few times, yet it hasn't scratched, the color hasn't faded, and the metal hasn't been damaged from the falls)
- not too bulky
- doesn't slip because it has a silicone bottom

Negative points that need attention:
- it leaks with hot beverages, despite following the usage instructions (that it shouldn't be at very high temperatures, etc.)
- initially difficult to clean the lid well due to its design [this can be resolved if you read the disassembly instructions carefully]

Would I recommend it to someone to buy? Depending on whether someone wants to spend a bit more to have a nice thermos, then yes (though this doesn't mean it is worth the money)

For its money, simply no! Basically, the product does not even do the basics of keeping warm, like not dripping! Within 2 weeks, it started to have leaks (which is unacceptable when Chilly's advertises it as 100% leak-proof). Also, the non-slip base started to come off.
