This is a nice wall sconce. It is much larger than I expected but it is ok where I am using it. It is probably too big for some other locations, ie. it might look silly next to a vanity mirror unless it was a very large area and a large mirror. It sticks out a ways and the glass is very large. 
The glass is not removable which leads me to believe it is not replaceable. The entire light might be a loss if the glass was hit and broken. 
It was very easy to install and came with all parts and in pristine condition.
