Installing a 4' Wire Shelf Kit, per instructions, just doesn't work. The "wall clips" provided and are directed to "push" into the drywall (first, that's impossible), once inserted don't hold, and then, again per directions, once you try to insert the wire shelf - which you have to POUND into the clips (they are so precisely manufactured) everything becomes loose. Not to mention, you haven't even started on the brackets yet. I bought these stupid shelves a few years ago. I just happened to have forgotten how bad they are. User's recommendation: Recommendation: Just by the shelf portion and do what you think is best to hang it on your wall. You're smarter than this.
