“This set takes up a very large area, which looks very impressive when built, I think it's also the most technically complex monorail ever built with the great option to drop of both the drive pods at various places on it route rather than just running round and turning back... More on itself. The train looks good but seems to be rather minimalist but that doesn't bother me it fits in nicely with the rest of the Unitron theme.”

Best of the Classics — “If you have the chance to get this set, GET THIS SET! It is probably the best set of the 90's, and possibly one of the best sets ever. It truly is an amazing set. If you can get it, get it. The front of the box flips up to reveal more pictures, and some transparent wrapping... More exposes the pieces, nicely sorted in a plastic tray.”
