according to cheetahs website under FAQ.
You can replace cheetah devices with standard devices . They also sell "speed anchors" to use in their boxes .
My only concerns would be quality of the devices and boxes and availability of the devices. If I were to use this system I think I would invest in those speed anchors just in case I can't get the cheetah devices and needed to use regular devices. That or order everything at once; the rough in boxes AND the devices/plates
Just my thoughts though
