There are two units, but only one outer box. Neither unit has an RF switch cable, so I haven't been able to confirm their operation. The unit without a box is the initial version. *It has square buttons. They might work if they had cables, but just in case, I'm listing them as [junk items]. I want to sell both units together, so please refrain from purchasing them individually. m(_ _)m They are quite old and show noticeable sun damage. Please purchase only if you understand that they are used and junk items. m(_ _)m Family Computer
