## Customer Reviews

### ⭐⭐⭐⭐⭐ Leak proof!
*by S***Y on 9 September 2025*

The media could not be loaded. It's a very good thermos. Beverage stays warm for around 4-5 hours, which is suitable for me. It is also leak proof as it claims to be. I carried it in my bag all day and took public transports and still there was no leak. This thermos also looks very stylish, the size and portion is just right.So far, I've used it only for a day. I hope it continues to be this good of quality.

### ⭐⭐⭐⭐ Keeps drinks hot, but could improve the lid
*by S***H on 10 June 2025*

The mug is great at maintaining the temperature of hot beverages for hours, and the build quality feels solid. However, the lid could be more secure—there’s a slight leak if not closed carefully. Still a very handy product for travel and office use.

### ⭐⭐⭐⭐⭐ Best product.
*by S***  on 14 September 2025*
