Amazon.co.uk:Customer reviews: LEGO DUPLO . The Lego stone quarry set was good. For the younger child an adult is needed to put it together. It is a toy that will last and grow with the child. The amazon price was good value towards all others I reviewed . Helpful. 0 Comment Report abuse. Maggiefox. 4.0 out of 5 stars LEGO DUPLO Stone Quarry.
