My son became addicted to trains shortly before his second birthday. I wanted to purchase a train set that would last for a while and would be easy to assemble and easy for HIM to use.
We purchased the first set of Geo Trax for his birthday and he LOVES it! The track is easy enough for him to put together himself and it STAYS together unlike some of the wooden sets I have seen. The track snap together with ease and can be set up in MULTIPLE configurations. We have set up the track in a different configuration every time we set it up! Younger children will need help creating layouts and making tracks meet back up, but setup takes little to NO time at all!
One of my favorite things about the Geo Trax rails is that ALL the sets work together, so we can coninue to add more and more and don't have to worry about certain parts not working with the current sets we own.
My ONLY negative comment about the Geo Trax system is the battery life for the remote control trains. You can expect to replace the batteries about every two weeks with the constant use of the trains. There are push trains that are also available, which my son, now 2.5, tends to use more than the remote trains.
All in all, this is a GREAT set for your little engineer and will grow with them!! Even dad's love to get in on the fun!
