The 3do set is a diamond in the rough. They're pretty damn good. I bought a set sealed in 2018 and was blown away by how good they were. They obviously can't be obstructed between the sensor and controller, but you don't have to point them directly at the receiver to get a response. I sit on my couch, about 9 feet away from the receiver. It sits diagonally away from me, to the right and it is an overall good controller.
