As of 2012, about 20 Reverchon spinning coasters are in operation, six of which are in the United States. Some other examples are Crazy Mouse at New Jersey's Steel Pier, Crazy Mouse at Pennsylvania's DelGrosso's Amusement Park, the indoor Exterminator at Pennsylvania's Kennywood, and the two side-by-side Primeval Whirl coasters at Disney's Animal Kingdom at Florida's Walt Disney World.
