These shelves arrived well packaged, with everything labeled correctly to efficiently put this together. We used my husbands handy drill to make putting it together faster. The directions were pretty standard as expected. But we had to guess that the shelf sat down in on the bottom shelf. That was really the only issue. We decided not to install the grid for the top. Everything seems very sturdy and there are straps to hook it to the wall so it doesn’t tip. All in all a great shelf unit.
