My 2 year old son adopted it immediately! Practical, lightweight, it can be transported easily (the garden to the veranda). Small enough to fit in a room inside but probably too small for children over 3 or 4 years ... The slope is quite steep, which offsets the small length of slides (though good feeling, apparently!). The scale is reassuring, even small hardly knowing climb stairs alone are able to climb it. My loulou will "brake" sometimes with the feet at the junction orange / green, and "rate" the finish! I do not know if it comes from his "gliding technical" or the slope of the curve (it does not do it every time ...) We have not yet tested the "aqua slide" but the principle seems simple to set up.
