I'm not sure why people gave it bad reviews saying it's wobbling, and not built strong enough.  All my pieces were well packaged and arrived undamaged.  My experience was completely the opposite.  Easy to follow instructions.  Once I turn the locking screw, the pieces held together very tightly.  I was able to complete the assembly myself in 45 minutes.  Once built, the shelf is very sturdy.  No stability issue and definitely not leaning like some other reviewer's photos.  Simple stand and open backing allows for easy cable handling.  Would highly recommend!
