I am using this as a ceiling light cover.  I had thought that it was flat... and was hoping that i would be able to bend it into more of a dome.  when it came... it was very heavy metal and impossible to bend - but it was already a dome! 

if you need a flat wall piece... this may not be what you want.  Fortunately for me, it actually was a dome shape, so it is perfect for my purposes.

Pros: great value, heavy, dramatic
