The only drawback was that there was a small bag of hardware (nuts and bolts) missing from our shipment.  I am sure that since this is a newer product, those who put the parts in left this bag out.  We ran to the hardware store to pick up the parts we needed and were on our way (we did have to go back as I forgot to mark some pieces that were missing - silly wife that I am).  We have a four year old girl and a 1 year old boy.  They both enjoy it.  My son only climbs underneath, but loves it.  My daughter loves racing to the top.  All in all - totally worth the money and time.
