My 4yo daughter got this for Christmas (so two weeks ago). I had asked some friends how to choose a three-wheel scooter, and one friend pointed out that having one configured to have two wheels at the front and one at the back was easier for the kids to use. His point was that the ones with two wheels in rear get in the way of kids kicking back to make the thing move forward. Instead, having one wheel in rear leats kids learn how to position their feet to scoot. That was excellent advice. This was the only one I found in that configuration, and I haven't always had good experiences with Radio Flyer products, but this one has been great. The height was right fromt the get-go. The base is nice and wide so my daughter doesn't have to struggle with balancing her feet. It is sturdy, not too heavy and not too light, so she doesn't go flying, but gets enough speed to be happy. Almost no assembly either--just unfold the front bar up, and off you go!
