I have long hesitated to take this model, given some reviews on the assembly. Finally, not too complex so as soon or read the instructions, and you have a screwdriver. From a strength point of view, I can not see myself forward as we have received today and that we have tested in the state "mom pushes". But we did, "tiled", "the bitumen", "grit" and "garden" with ... and to share the garden or pushing in the grass seemed a little random, the vehicle s 'comes out with a good overall score. Point + are the very very silent wheels. For me it's a great buy, I am delighted, my daughter than a year, it seems, was also delighted his first outing. She is very tall for his age, and his feet do not hang at all the ground position "baby led" On the contrary, there is the margin. So frankly, delighted with the product, strength testing in time ... CONCLUSION: Do not hesitate with a price similar product if you are not sure of the wheels silent !! (I have a truck with plastic wheels, it's a nightmare on the gravel)
