This one came with one shelf missing 2 screw holes so I couldn't put it together properly.  It took months of back-and-forth communication - several times I was notified that the new shelf was in the mail ... only to find that it wasn't - and that it was on backorder.  After a long period of time, the Wayfair rep (after some discussion) wouldn't take the unit back unless I packed it up again and paid for the shipping.  I was afraid to buy another new unit - so he finally agreed to give me 30% off.  I had a hard time finding a place that would drill holes in the shelf so I could use it.  At the end of the day, I do like it.  Since then,  I have not ordered very much from Wayfair - and I do pay attention to the reviews.  4+ months from purchase day to when I could finally set it up.
