Pros : The screw is secure and safe, I have a 4.5"x3.5" double thick fused project on mine with no fear of it falling off like clips always give me.
The bases themselves have a piece that comes out to press flat against the back of the glass to help provide support and keep the shade from turning if bumped.
The on/offrocker is convenient and marked and the white base is a true white, not grey or almond looking.
Cons : It takes incandescent type bulbs so it sticks out a bit far from the wall, not an issue with mine, but I suppose it could be for some folks
Other Thoughts : I love night lights, they're the perfect way to show off both the lit and unlit versions of things!
