I paid an electrician to install this and the light is perfectly level, however the vertical support lines are bent.  Maybe this is a manufacturer issue.  The electrician is going to come back and look at this one again.  Also, the glass surrounding the bulbs is not held in place by anything.  I am sure my son is going to kick a soccer ball at some point and break the cylinders.  The electrician recommended gluing them down, but this will make changing the bulb and cleaning the fixture extremely difficult.  This is a design flaw.
