We first saw it at a friend's place in London and the little one loved it as a bath time activity. It easily sticks to the tiles of the bathroom (only when the pieces are wet), and keeps her entertained for a while. However, in our case, the pieces are slightly "scratched", not completely flat, which results in them not sticking well and sliding on the tiles. Maybe because it is still new and the pieces were dry for a long time in the box? We will see if the situation changes. Overall, it is a nice toy for the bath and educational (we have conversations while building the map, about countries, languages, animals of each continent, etc.)
