I've known the eau bottle for some time now, because my husband uses one himself and really enjoys it. It definitely keeps your drinks hot/cold for the day. So I chose the winter white bottle - pretty colour, light grey engraving of the coordinates to the well you're supporting, easy to clean. I love the look and slightly textured feel of it. (see pictures) And if it's closed, it's closed - no leaking.
Although my package got stuck in the mail, the service was great. Definitely friendly and eager to help. Once I requested for the team to check if it might have got lost while being shipped, the bottle arrived in two days - being sent all through Europe.
All in all I really enjoyed the service, it's an awesome product and I'll get a lot of use out of it. Worth the little investment!
