Question about Hyperice Normatec 3.0 Leg System

Hello together What exactly does the scope of delivery look like? I am mainly interested in the control unit (Control Basics). The description says that no control unit is supplied, but it is visible in the pictures and a power supply unit is also described in the scope of delivery. If not, would I have to buy the following? https://www.digitec.ch/de/s1/product/hyperice-normatec-30-control-basics-massagegeraet-36502352 What would be the difference to the Leg Attachments? https://www.digitec.ch/de/s1/product/hyperice-normatec-3-leg-attachment-short-pair-massagegeraet-23931898 Thanks for your support :-)
