My parents offered to my son for his 2 years. Easy to install, slightly less to fold and unfold. We must tighten the bolts because the handlebars sometimes tends to loosen. 5 months later, I would say I am very satisfied. It is quite stable, robust (it suffered in falls) and learning balance is easier with 4 wheels (even gently sloping). Apparently she is evolutionary but we have not yet tested. The colors are nice, it's a toy that will appeal surely. The only downside is that it is not very portable and a bit heavy, so that you do not always smoothly when traveling. Seller good, the first product was a delay in delivery, a second was sent and arrived in time!
