We absolutely LOVE the Geotrax system. My sons are 3 and 7.5. We purchased (recieved as gifts) our first set last Christmas with the Grand Central, all the GeoAir, remote control, barn etc. as well as lots of tracks. My kids play with the trainset EVERY DAY. To be honest, we love the the timber rail way design, BUT the quality of the new tracks are not acceptable. Last year's quality was 100% better. Even my 7 year old commented that something was "wrong" with the new tracks, that hey don't connect right. The new tracks are one solid piece of plastic, vs. the older version has some sort of spring to connect the pieces (I am sorry if I am not describing this correctly). Thus, my ONLY complaint on the new product is the "new" quality - I REALLY hope Fisher Price reconsiders and goes back to the original design. Other that that we are extremely happy with the Geotrax system. We have had several track designs in our living room and many hours of play.
