The Nissan all weather floor mats are made by Weathertech. Nissan just rebrands them. There is an entire thread with photos... here is the link from the Rogue FAQ sticky:

I would suggest buying direct from Weathertech or another online retailer. The Nissan version is more expensive.
As for fit & performance? They are a good product. They fit perfectly. My only qualms were I wish the drivers side dead pedal was fully protected and the rear mat was a bit larger. The mats can be difficult to remove & install as they are quite rigid.
