Easy and good looking.
Color: Black, Size: 24" W x 7" D x 1.5" H (2 pieces)
Installation is pretty straight forward. Small level is included to make sure they are put up correctly. They look good up on the wall.

Shelf wobbles and sits at an inclined angle after mounted.
Color: Oak, Size: 28" W x 7" D x 1.5" H (2 pieces)
While the shelf looks nice, it didn't work as it should. I anchored and screwed in the black metal bracket pretty well, and it stays perpendicular to the wall and doesn't wiggle or wobble one bit. But as soon as I slide in the wooden shelf, the whole shelf wiggles and settles at an inclined angle. Putting in the two screws down on the shelf did nothing to help with the wobbliness. I may have to glue down certain big decoration in fear of it sliding down the shelf, though that may be a bit overcautious and exaggerating.
