Query: Ouch!!

Santa got this for our 4 yr old but mom or dad are the only ones that can really build with it. It is way to hard for a kid to put together. I had a broken nail and bruised palm from trying to get one vehicle made. He likes to play with it after I am done but the reason we got it was so he could build with it. Bummer. Next time I'll stick with the tried and true Tinker Toys.
