Query: too good to be true

At first, I marveled at how easily these shelves were assembled and the neat clean finish when attached to the wall. It claims "no tools required", which is basically true, but it's easier with a philips head. They have, what I can only describe as threaded "push pins"; 4 that screw into the wall and 2 for each support. There is a hollowed out groove along the back edge of the shelf, where the pins are inserted and 2 holes each, for the supports. I followed the instructions meticulously. After just a few days of holding some of my boys' smaller trophies, maybe totaling 5 lbs. or so, (I believe the directions said they should be able to hold up to 30 lbs.) they started tilting downward and separating from the supports. I tried some industrial strength adhesive to reinforce the bond with no luck. I ended up building my own shelves. These are not worth the money at all.
