I bought my son's version of this toy first from Toys R Us for my son for Christmas. It was so awful we returned it and bought this one. Yes, this one was a bit more expensive, but it was worth it! This is a high quality plastic that is easy to put together. The balls are made of real glass and can be easily replaced if lost. We are building it with my 2.5 year old son (who can only help a bit). I predict it will take years to grow to this point and I am absolutely confident that the quality will stand the test of time. As for the guy who said you should glue it together. Half the fun is rebuilding it every time! If you have a kid who loves building things, that's a win!
