Easy to assemble. Minimalist look. I dont think they are sturdy enough for heavy objects. I am putting light weight toys on them.  The shelves themselves are held onto the brackets with short screws and did have a wobbly feel to them when I was moving them into place, like I could press too hard on one side of the shelf and it would have broken off.  The metal supports absolutely have to be anchored to the wall or the shelf will tip over.  I used my own drywall anchors instead of the flimsy ones that were included.  The metal poles fit together ok but they do look like they were manufactured quickly.  Overall for what I wanted these for and the price. I am happy with them, but if you are picky about details you may want to go with the pricier version.
