This is the front view of the Stiga Elite Roller table tennis table. It is possible to see the finish of the playing surface, which is a nice even blue color, without being too glossy (which can cause unwanted reflections and glare). The white painted lines have been done so that the overlap between them and the rest of the playing surface is virtually unnoticeable. You certainly won't get a bad bounce from hitting the edge of the white lines - I can't vouch for hitting the edge of the table though!
This photograph also shows the undercarriage of the Stiga Elite Roller table clearly. The undercarriage is pretty strong, with welded joins, bolts and crossbraces. The metal tubing is not quite as thick as the tubing used in the Stiga Expert table, but it's still more than thick enough to do the job of supporting the playing surface well. And although I don't recommend sitting on the edges of the table, I must admit I've been guilty of doing just that on my own table, and it has survived intact!
It is hard to see the height adjusters at the bottom of the legs closest to the camera, which allow you to get a level playing surface even if the floor is not quite even. But they are there - take my word for it.
