I was a die-hard fan of camelbaks… until I met contigo. The bottle itself looks ordinary relatively to the rest of the products in the market, however, it was designed to do one thing really well: spill-prevention.
The auto-seal design of this mug is an effective measure toward preventing user errors of not closing the lids tightly during a rush. With this simple mechanism, I can absent-mindedly throw the water bottle into my backpack without any worries. It also has a minimalistic, modern design that is not detestable.
However, I really wish that they come out with a “hook” or some sort of handle at the top to make it easier to be carried around, and perhaps a design for the button that makes it looks less like a “gadget”.
