I bought two of these and had each attached to a broad window sill of two very tall windows.  I filled them with my collection of art glass.  Now I have storage/display for my collection, and they somewhat block our view of the building next door without blocking the light. 

Pros: Great value and attractive design for the money.
Cons: Since these are not solid wood, some extra steps were required for drilling and attaching into the sill.  However, solid wood would have cost about three times as much!
