Overall, looks great at first impression, though not the best quality shade when you look at it for more than a few seconds.  It has dark spots and a really obvious ￼off-center dent that bends the light.   Id expect this quality of glass to be part of a cheaply made unit.  

This works great for a spot light effect around something since the ring blocks light from ambient my lighting the room.  Works well with color-changing bulbs!
