My 4yr old boy bought this from his own pocket money and absolutely loves it! His older brother (5yr) had to help him with building some parts which was great for us to see, both boys playing together so well! After having build it all, they especially love putting the 'grain' in the silo and putting the trailer under it, opening the silo and letting the grain all fall into the trailer. Also the little cat and mouse are very cute! We all love building lego and spend hours playing with it. The only draw back I find it that is all comes apart very easily (seems much easier than the lego we have from when I was a girl) and needs to be handled with care. Then again, the boys don't seem to mind and happily build it all again. The roof comes off the tractor very easily so the farmer can be put in and taken out quickly. The roofs of the farm can be flipped up. All in all, very good value for money.
