I have several light strip pluses. They all have ribbon cables between the controller and the light strip. The ribbon cables can be unplugged from the controller. This is a big plus as it allows extension cable so you can better hide the controller. It also allows splitters so you can run strips in different directions from the controller.
I recently got another strip (and returned it) that had a round cable between the controller and the strip. The round cable could not be detached.
Is the round cable an older or newer version then the ribbon cable? Is the a way to tell from the package which one it is?
