Adequately prefer the capacity of 650ml and not 500 as the 650ml is a shorter packaging and fits more easily on shelves and cabinets. Needless to say, it is self-evident that it has a larger capacity.

Very good water bottle, it doesn't leak a single drop! This design doesn't fit in the cup holder of cars.

Very good quality materials, very convenient, and keeps the temperature a little longer than a conventional water bottle. However, it is not insulated. It is very easy to clean, does not smell like plastic, and has a wide variety of colors and sizes. Additionally, it is convenient that it can be hung, although I would prefer if there was a way to remove the strap so that I don't get it wet when washing it.

Very good. Very good quality material. The only downside is that after a short period of use, the button that opens the lid gets stuck and doesn't always open.

One of the best water bottles on the market for use at school. It is good to also purchase its replacements (silicone parts) as children tend to remove them and they may get lost.
