Sounds like you received the wrong product.
The roof shade I received has suction cups permanently attached. I believe the video showed the cups being attached after adding a support flap and a ring, but that must have been an old version. Mine have none of that. There is no way to remove the suction cups on the version I received and I like it much better.
The roof shade is in two parts. Each part has 6 permanently attached suction cups.
I bought side window shades as well and they are built similarly but have 4 suction cups.
