Space Rails 231-9 Level 9 (-) Rollercoaster Buliding Game, Multicolor, 70,000 mm

Very poor quality parts that are badly made and break easily. Instructions are poor and the design of some of the stunts makes it almost impossible to get them to consistently work. Be prepared to constantly tweak everything to make it function and don't be surprised if altering one part, stops another part of the system working. Flimsy, frustrating and very disappointing. Having said that, my grandson doesn't seem to mind at all, as the failures have made it extremely interactive, so all was not lost. :)

Bu far the worst thing I have ever bought, the double loop has a design fault, many people have failed to get it working.The clips keep breaking.If you want a heart attack due to stress. Then buy this!
