We bought this tractor for our youngest son's 2nd birthday a few weeks ago and he absolutely loves it. It was a piece of cake to put together, and if you're like me, applying the decals is an absorbing ten minutes. The build quality, whilst not exceptional, is perfectly acceptable considering the price.
My only gripe with this toy, and my reason for giving it 4 stars, is that it utterly destroys shoes. Our son uses it on a concrete driveway and I'm not exaggerating when I say he completely ruined a pair of new runners and the socks underneath in less than 20 minutes. He has a couple of other ride-on toys he inherited from his older brothers and this has never been a problem before. I can only conclude that because the seat is slighter higher than his other ride-ons, the wheelbase has had to be made wider to avoid tipping. This means toddlers have to place their feet at a bit of an awkward angle either side of the front wheels, and push themselves not with the soles of their shoes but with the toe of the shoe. I imagine this isn't an issue if you're using it as an indoor toy on carpet, but if you're planning on letting them loose in the garden with it, either invest in some infant-sized, steel toe-capped work boots, or teach them the hard way and send them out in a pair of old sandals.
