after reading the reviews on these I figured I'd give them a try .,I ordered them in two .different sizes ,  They are perfect for what I wanted them for , As I teach an art class painting on glasses and need to transport them home to finish the project  ,then back to the class for pickup. The  window is great to see which through and  feel confident  transporting my students artwork in them as they are sturdy enough. Love them !!  

Pros: sturdy , and view window is a big plus 
Cons: would like to have choice of colors , but still very happy with them
