Excellent Quality.  The chain links are substantial. The unit is very light in weight but built well. It uses the typical hardware & technique for hanging such a light.  I don't know why the specs says it's NOT dimmable -- dimmable is a function of the light bulb (and switch used) and not a function of the fixture itself.  If you have dimmable light bulbs (preferably LED) and a dimmer switch (ideally made for LEDs), you will have no problem making it dimmable.  I'd recommend  using an A15 size LED bulb (about the size of an applicant bulb) vs a normal A19 size bulb. A15 Led do come in 60 watt equivalent but the lumens  can vary from 600 to 800 lumens.  A normal 60 watt bulb puts out 800 lumens.  I prefer soft-white color (2700K) vs warm-white (3000k).  Highly Recommend.
