Ulla works with bottles of any shape, size and material.
Ulla fits your bottle, knows when you drink and blinks when you need more H2O – in your body and in your life.
Because, even after getting yourself a cute bottle, water is still the last thing on your mind.
I love love love my pink Ulla :) It has done everything that was claimed it would do - remind me to drink water. I've just ordered 2 more for family.
