The product is as described, very nice lighting fixtures.  One main problem with the product is its mounting system.  This fixture is fairly wide but mounts on a center post (nipple) one central point of attachment to the electric box, which allows the light bar to easily swing especially when the weight of the glass shades are added.  No matter how much you tighten the center nut you have to be very careful to not allow the fixture to rotate on the wall.  Poor attachment design for the weight and size of the fixture.  Be careful if you take one of the lamp shades off either end of the fixture which can cause it to seesaw and damage the ceiling, the fixture or the wall.  Other lighting fixtures of this type we have installed, have 2 points of attachment to fasten it to the electric box making a stable wall connection, the fixture cannot rotate.  Had I noticed this feature prior to purchasing, I would not have made the purchase.
