Grill high quality that comes with 2 pairs of grill plates. A pair of ribbed and two plain. The serrated used for grilling with the lid closed, just like a regular vikgrill. The smooth is used when weight out the grill so it can be used as a table grill, you can iofs use the ribbed with which is a matter of taste.
The cover then goes to open so much that you get double the horizontal grill surfaces, smart solution.
The downside of it is that there's nothing that collects fleet from the lid if you are grilling a while and then open the lid. Then run all fleet down the back only.
