Ordered to my son for Christmas, complete with rail and tunnel ... He loved it. I chose the train because he wanted a remote-controlled train, I wanted resistant so he could play with his friends without risk. Test made on Christmas day with the cousins, 4 above, no worries ... it's a toy that they can play without the need for adult supervised, it seemed to me important. By cons I am disappointed with the remote control that operates at infrared, as soon as the light changes and it does not work you almost paste the remote control on the train to react, one can damage it almost goes faster with buttons on the train ...
