Shipped on time, and received on time.  The shelf was easily installed.  I used four drywall anchors and one stud, and it is very sturdy.  I used a simple level, and it was very easy to get it right the first time.  The shelf slides over the installation bracket (from the front, so there's no requirement to have additional clearance on the sides).  It looks absolutely fantastic.  Very sturdy.

Pros: Great value, easy to install.
