Perfect for the right person
Overall<br /><br />  The "rock" set is perfect for someone who enjoys the process of building as much as the result.  While you can build quite tall structures with the set, building anything more than 4 "rocks" high requires a lot of concentration, patience, and a good eye for shapes.  As other commenters have noted, the set makes for a great game of how high can you build; it's also quite calming to build by yourself.<br /><br />Pros<br />  Solid construction<br />  Well-made<br />  Perfectly finished<br />  Comes exactly as described<br /><br />Cons<br />  The set I received doesn't have much variety.  The "rocks" were all approximately the same size (about 3 inches in length).  A greater variation in size would have made this set much more interesting.
