### ⭐⭐⭐⭐⭐ Good
*by F***A on 20 September 2025*

Best tumbler, keep water cold and hot all the time

### ⭐⭐⭐⭐⭐ Very Good
*by M***E on 25 September 2025*

This is very good for keeping water cool for long periods and it's really big.

### ⭐⭐⭐⭐⭐ Perfect for winter walks
*by I***N on 21 November 2024*

The baby blue is definitely the winner. Holds the temperature pretty well for 24 hours, 100% leakproof, simple and easy to clean. I wish there was a blue tilted straw, but for the this price its it perfect just as it is. Also the logo design looks sick 🔥
