Review: El termo en general es buen producto, cumple la función de mantener un par de horas tu bebida caliente (no lo he probado con bebida fría pero no creo haya problema). La tapa viene con un seguro en su interior para evitar derrames, y hasta el momento ha funcionado perfecto. Cómo se nota en las fotos el color nada que ver con el de la publicación, que muy probablemente es por la iluminación utilizada para esas fotos. Al final si me gustó el producto y si lo recomiendo.
Review: The quality of the tumbler is nice. Completely leak proof and my tea stayed hot after 4 hours. I tried pouring warm water to the tumbler overnight for about 7 hours and next day morning the water was still warmer than room temperature. Downside for me is that I have smaller hands so the tumbler is a bit too large for me to grab comfortably. Also the colour was not the same as displayed in the picture, it is much darker. Overall, I would recommend this product.
