The amazing price of $900 makes it more of a toy for collectors than a toy for children. The companion Trailer and Roller set for Optimus Prime has the same cool auto-conversion features and a steep $750 price as the original set.

The trailer is three feet in length and fully extended. It unfolds and tilts vertically into a nearly flat rectangular shield, complete with an integrated, articulated sentry blaster. In truck mode, it houses the Roller vehicle and human sidekick Spike who is ready to jump into action or enjoy the ride.

You can use an app to control the truck and roller car, or open the rear swing doors with a voice command. It auto-converts in seconds, and you can use it to shoot at the Decepticons during the chase.

The price of the trailer and robot appears to be justified. The company promisesmeticulous craftsmanship, high-grade metal allow parts and cutting-edge robotic tech. It has over 2,000 components and uses 18 of Robosen's proprietary servo motors and 60 microchips.

Pre-orders are open for the $750 trailer and roller set, but they won't be delivered until around November 2022. The package includes a protective storage case with handle for easy transportation, as well as a collectible pack that includes an individualized serial number, metal challenge coin and sticker pack.

The limited number of Flagship Optimus Prime robots that were released by the two companies were sold for $750. Many of these items will stay in their collectible protective cases, never to transform into anything but cash, despite all the cool features.
