Sorbus Floating Shelf Set, Rustic Wood

The shelves themselves are mostly fine, they look as advertised on the wall and the laminate wood is nice. I haven't rigorously tested their weight, but they don't jiggle. I docked one star because it isn't totally flush with the wall (a few mm off) and one of the two screws that keeps the shelf in place wouldn't screw in flush with the board, leaving the sticker cover noticeably loose. I docked the other star because their claim that installation takes less than 5 minutes is entirely false. It took me at least one hour to install one shelf: I had to mark all 8 drywall holes on the wall very accurately and using a level, drill pilot holes (I didn't do this at first and one of the holes was misaligned), drill the full holes (I used a 1/4in bit), hammer in the anchors, screw in the mount (by hand because the mounting pipes blocked my power drill), attach the shelf with the two bottom screws (which took several tries to get close to flush), then clean up the drywall mess. Plus double check everything along the way because I don't want eight 1/4 in misaligned holes in my wall. That's all fine and somewhat expected, but they shouldn't make false claims about the installation ease and time. Any review that says it took them 5 minutes is by an extremely experienced handyman or a liar.
